The transparent battlefield has changed everything

Monday, September 4th, 2023

The War in Ukraine, Edward Luttwak notes, is a war that must be fought by sheer, grinding, attrition, just like the First World War on the Western Front, with almost none of the maneuver warfare exploits that made celebrities of Guderian, Rommel, Patton, and Rokossovsky in the Second World War, and Arik Sharon in 1967 and 1973:

All those masters of war won disproportionate victories with surprise offensives. Arriving in fast-moving columns, their forces greatly outnumbered and overwhelmed a specific sector, while the bulk of the enemy, distributed across an entire front, could not intervene in time.

In other words, “manoeuvre warfare” depends entirely on surprise. Even in the Second World War, there was reliable aerial photography, so that pre-battle concentrations of tanks, trucks and artillery tractors could not escape detection as they gathered over a period of weeks. But once the offensive columns moved, it was hard to keep them under observation, let alone predict their destination. Photography was impeded by night, clouds and enemy fighters, leaving more than enough uncertainty to deceive enemies with decoys, simulated radio traffic, and the false tales of double agents.

This is how it came to be that on D-Day, 6 June 1944, the strongest German Panzer columns ended up being massed behind Calais to face Patton’s fictional First United States Army Group, while the Allies were landing in Normandy 230 miles away. Douglas MacArthur’s Inchon landings in September 1950, which nullified a string of North Korean victories in the preceding months, likewise achieved total surprise by very elaborately simulating a landing at Kunsan, 100 miles to the south.

None of this could happen now. The Americans, Russians and other military powers have observation satellites equipped with synthetic-aperture radars, capable of revealing single tanks, let alone any large grouping of forces, regardless of visibility, while their returns are refreshed often enough to detect troop movements in hours if not in minutes. Any other information drawn from intercepts, aerial reconnaissance or ground observation merely supplements this reliable intelligence. It is enough to make the battlefield transparent and operational surprise impossible, killing off the manoeuvre warfare that can win battles quickly and without mounds of casualties.

In early summer, when the Ukrainians deployed the precious “operational reserve” they had built up, there was no great mystery as to what they would do with it: attack somewhere south of Zaporizhzhia and fight their way down to the Black Sea.

[…]

While the Ukrainians were training and deploying, the Russians south of the Dnipro were digging trench lines shielded by minefields that stretch roughly 625 miles — 185 miles longer than the Western Front at its greatest extent. Napoleon called this style of linear defence a “cordon”, a thick rope made of infantry to hold the enemy along a long front. And, in his own time, he rightly explained why cordons were the stupidest way of defending a front: the enemy would arrive in columns and easily cut through the few troops holding the particular sector they attacked.

But once again the transparent battlefield has changed everything. Watching the Ukrainians advance in real time, the Russians could send their forces to intercept them in equal if not greater numbers. And even if the numbers were equal, the combat would be unequal because the Russians would be shielded by their minefields and by their trenches.

People think that satellites are secure

Saturday, September 2nd, 2023

In a presentation at the Black Hat security conference in Las Vegas, Johannes Willbold, a PhD student at Germany’s Ruhr University Bochum, explained he had studied three types of satellites and found that many were utterly defenseless against remote takeover because they lack the most basic security systems:

“People think that satellites are secure,” he said. “Those are expensive assets and they should have encryption and authentication. I assume that criminals think the same and they are too hard to target and you need to be some kind of cryptography genius. Maybe it wasn’t a good idea to give this talk.”

Satellite operators have been lucky so far. The prevailing wisdom is that hacking this kit would be prohibitively expensive due to the high cost of ground stations that communicate with the orbital birds, and that such hardware benefited from security by obscurity — that getting hold of the details of the firmware would be too difficult. Neither is true, the research indicates.

For example, both AWS and Microsoft’s Azure now offer Ground Station as a Service (GSaaS) to communicate with LEO satellites, so communication is simply a matter of plonking down a credit card. As for getting details on firmware, the commercial space industry has flourished in recent years and many of the components used on multiple platforms are easy to buy and study. Willbold estimated a hacker could build their own ground station for around $10,000 in parts.

As an academic, Willbold took a more direct approach. He just asked satellite operators for the relevant details for his paper [PDF]. Some of them agreed (although he did have to sign an NDA in one case) and the results somewhat mirrored the early computing days, when security was sidelined because of the lack of computing power and memory.

He studied three different types of satellite: an ESTCube-1, a tiny CubeSat 2013 running an Arm Cortex-M3 processor, a larger CubeSat OPS-SAT operated by the European Space Agency as an orbital research platform, and the so-called Flying Laptop – a larger and more advanced satellite run by the Institute of Space Systems at the University of Stuttgart.

The results were depressing. Both the CubeSats failed at a most basic level, with no authentication protocols, and they were broadcasting signals without encryption. With some code Willbold would have been able to take over the satellites’ basic control functions and lock out the legitimate owner, which he demonstrated during the talk with a simulation.

The Flying Laptop was a different case, however. It had basic security systems in place and tried to isolate core functions from interference. However, with some skill, code, and standard techniques, this satellite too proved vulnerable.

The first Japanese feature-length animated film was made for the the Japanese Naval Ministry in 1944

Friday, September 1st, 2023

The first Japanese feature-length animated film — the first animé — doesn’t get much attention these days, even though it’s beautifully made, in a Disney-inspired style, because the film, Momotaro: Sacred Sailors, or Momotaro’s Divine Sea Warriors, was made for the the Japanese Naval Ministry in 1944 and released in 1945, a few months before Japan surrendered:

About 45 minutes in they start preparing for an airborne attack against a European colony.

The bumbling Brits who surrender to the Japanese are depicted…with a horn on their heads?

The Japanese did have marine paratroopers in World War II, by the way:

The troops were officially part of the Special Naval Landing Forces (SNLF or Rikusentai).

[…]

Paratroop units were only organized on the very eve of the war, beginning in September 1941.

[…]

Two companies, numbering 849 paratroopers, from the 1st Yokosuka SNLF, carried out Japan’s first ever combat air drop, during the Battle of Menado, in the Netherlands East Indies, on January 11, 1942.

In street warfare the Germans forfeited all their advantages in mobile tactics

How Hitler Could Have Won World War II by Bevin AlexanderThe Stalingrad campaign, Bevin Alexander explains (in How Hitler Could Have Won World War II), is one of the most poignant examples ever recorded of a ruler engineering his own destruction:

When the army chief of staff, Franz Halder, protested the self-defeating operations, Hitler removed him. Only in the late stages when the German 6th Army had been isolated and a quarter of a million men were about to be lost was Erich von Manstein able to induce Hitler to grant just enough leeway to keep the entire southern wing of the German army from being destroyed as well.

After Stalingrad, Germany surrendered the initiative in Russia. Hitler never could summon enough strength thereafter to alter the balance of power against him. Despite heroic efforts by his soldiers, he had doomed himself to the slow, inevitable destruction of his army and his regime.

Two elements of the 1942 campaign stand out. First, Hitler committed the oldest and most obvious mistake in warfare: he neglected the principle of concentration and split his efforts between capturing Stalingrad on the Volga River and seizing the oil fields of the Caucasus.

[…]

This brought on the second element of the campaign: Hitler, instead of being satisfied with an advance to the Volga and interdicting traffic on the river, which had been his stated aim, insisted on 6th Army capturing the city itself. This forced it to concentrate in the built-up area at the end of an extremely deep salient, offering the Russians an invitation to lock 6th Army in place by launching a street-by-street urban battle.

[…]

Yet Hitler refused to allow 6th Army to withdraw, and — because he had committed his other forces to the Caucasus — had insufficient troops to strengthen either flank of the salient.

[…]

At every stage Hitler made disastrous decisions — dividing his army in the first place, insisting on seizure of Stalingrad, refusing to allow 6th Army to retreat, failing to go all out to save the army once it had been surrounded, and refusing to heed evidence that the Russians were about to isolate the two army groups in the far south.

[…]

The German army in the east (Ostheer) came out of the winter of 1941–1942 with 2.4 million men on the front, counting replacements, more than 600,000 fewer than had started the campaign in June 1941. The situation was worst among infantrymen, whose numbers had fallen 50 percent in the south and 65 percent in the center and north. This weaker army had to defend a line that, since Hitler prohibited straightening out loops and protuberances, wove in and out for 2,800 miles from the Baltic to the Black Sea.

The quantity of German weapons was declining as well. Tank production was below 600 units a month. When Halder told Hitler Soviet tank manufacture was more than three times as great, Hitler slammed the table and said it was impossible. “He would not believe what he did not want to believe,” Halder wrote in his diary.

At least the Mark IV tanks had been rearmed with long-barreled high-velocity 75-millimeter guns and could meet the Soviet T-34s on better terms. But nearly a third of the artillery pieces were old French cannons, the number of combat-ready aircraft had fallen to half what it had been in June 1941, while shortages of fuel and ammunition were great and growing.

[…]

Hitler now made an irretrievable error. He had concluded, because of the initial success of the offensive, that Soviet strength had been broken, and diverted Hoth’s 4th Panzer Army south to help Kleist’s 1st Panzer Army cross the lower Don to open a path to the Caucasus.

“It could have taken Stalingrad without a fight at the end of July,” Kleist said after the war. “I did not need its aid, and it merely congested the roads I was using. When it turned north again, a fortnight later, the Russians had gathered sufficient forces at Stalingrad to check it.”

Panzer leader Friedrich-Wilhelm von Mellenthin voiced the opinion of nearly all senior officers in this campaign. When Stalingrad was not taken in the first rush, it should have been shielded with defensive troops and not attacked directly.

“By concentrating his offensive on a great city and resorting to siege warfare,” Mellenthin wrote, “Hitler was playing into the hands of the Russian command. In street warfare the Germans forfeited all their advantages in mobile tactics, while the inadequately trained but supremely dogged Russian infantry were able to exact a heavy toll.”

[…]

In his original plan, Hitler intended four armies to press into the Caucasus, while one went toward Stalingrad. Now three armies marched on Stalingrad — an objective of infinitely less importance than the oil fields — while two armies drove into the Caucasus.

This was lunacy to every professional soldier, and Halder protested to Hitler. But the Fuehrer paid no attention, and also ignored evidence of powerful Soviet formations to the east of the Volga and in the Caucasus.

[…]

General Gustav von Wietersheim, commanding 14th Motorized Corps, watched his strength decline. He recommended that 6th Army be withdrawn to the west bank of the Don, forty-five miles away. The only result was that Hitler removed him because he was “too pessimistic.”

As the German offensives stumbled to a halt, radical changes in leadership came about. On September 10 Hitler relieved List, because his army group had not captured the whole Caucasus. He did not name a successor, and commanded the army group himself in his spare time from supreme headquarters.

Hitler’s long conflict with Halder came to a head. Hitler reproached Halder and the army general staff, calling them cowards and lacking drive. When Halder presented proof of new Soviet formations totaling 1.5 million men north of Stalingrad and half a million in the southern Caucasus, Hitler advanced on him, foaming at the mouth, crying out that he forbade such “idiotic chatter” in his presence.

Halder, who looked and acted like a prim schoolmaster, persisted in explaining what would happen when the new Russian reserve armies attacked the overextended flanks that ran out from the Stalingrad salient. On September 24, Hitler dismissed him.

Hitler said arguments with Halder had cost him half his nervous energy. The army, he said, no longer required technical proficiency. What was needed was the “glow of National Socialist conviction.” He couldn’t expect that from officers of the old German army.

The new chief of staff was Lieutenant General Kurt Zeitzler, a tank expert and man of action. Zeitzler soon took note of the cliques and intrigue in Hitler’s headquarters, became excessively cautious, and did nothing to challenge Hitler’s decision to keep 6th Army at Stalingrad.

Yet, as Field Marshal Manstein wrote: “A far-sighted leader would have realized from the start that to mass the whole of the German assault forces in and around Stalingrad without adequate flank protection placed them in mortal danger of being enveloped as soon as the enemy broke through the adjacent fronts.”

A drone in the air has a more accurate picture of the direction and strength of the wind

Tuesday, August 29th, 2023

Andrei Bogdanov, CEO of Barcelona-based drone company UAVHE, is not developing his Baduga flying rifle for the military:

The problem Bogdanov is trying to solve is the control of feral pigs. The Twitterverse mocked an American user who suggested that he needed an assault weapon to prevent his yard being invaded by “30-50 feral hogs” in 2019. But controlling these animals, which cause an estimated $1.5 bn in damage in the US alone each year, is a major challenge.

Hunters usually only kill a few in a pack, causing the rest to scatter. In Spain where Bogdanov is based, hunters shoot some 400,000 wild pigs every year, but this is not enough to stop the population rising.

[…]

Bogdanov, has developed Baduga, a hunting rifle mounted on a small drone. A smart suspension system keeps the weapon’s center of gravity below the point of attachment, and gyro-stabilization ensures that the barrel remains stable regardless of wind or motion. The sights, including a multispectral camera able to see in the dark, are mounted on the barrel.

Bogdanov says that the firing platform is effectively decoupled and independent from the drone, firing as easily as it would from a tripod. The system automatically compensates for recoil, and has a magazine of 60 rounds. A further development may see automated in-flight magazine changing.

Early versions of the design employed off-the-shelf gyros, the latest iteration is custom-built for this application and weighs around 4 kilos, with the rifle adding a similar weight. The platform is a standard heavy commercial drone, similar to those which carry movie cameras and survey instruments.

[…]

Bogdanov says his setup achieves an accuracy of better than 0.1 minutes of arc, so the limitation is the accuracy of the rifle and ammunition.

[…]

“Unlike ground shooters, a drone in the air has a more accurate picture of the direction and strength of the wind over the altitude spectrum — it is easily calculated from the drift of the aircraft relative to the ground,” says Bogdanov.

[…]

So why not go down the obvious route and develop this specifically as a weapon system for the defense sector?

“Despite a common myth, developments for the military do not bring in a lot of money,” says Bogdanov. “We have shown it many times, but so far the matter has not gone further than talks and interest from military customers connected with it.”

The tools of the academic-reactor designer are a piece of paper and a pencil with an eraser

Monday, August 28th, 2023

In 1953, then-Captain Hyman Rickover explained the difference between an academic reactor and a practical reactor:

An academic reactor or reactor plant almost always has the following basic characteristics:

  1. It is simple.
  2. It is small.
  3. It is cheap.
  4. It is light.
  5. It can be built very quickly.
  6. It is very flexible in purpose (“omnibus reactor”)
  7. Very little development is required. It will use mostly “off-the-shelf” components.
  8. The reactor is in the study phase. It is not being built now.

On the other hand, a practical reactor plant can be distinguished by the following characteristics:

  1. It is being built now.
  2. It is behind schedule.
  3. It is requiring an immense amount of development on apparently trivial items. Corrosion, in particular, is a problem.
  4. It is very expensive.
  5. It takes a long time to build because of the engineering development problems.
  6. It is large.
  7. It is heavy.
  8. It is complicated.

[…]

The tools of the academic-reactor designer are a piece of paper and a pencil with an eraser. If a mistake is made, it can always be erased and changed. If the practical-reactor designer errs, he wears the mistake around his neck; it cannot be erased. Everyone can see it.

The academic-reactor designer is a dilettante. He has not had to assume any real responsibility in connection with his projects. He is free to luxuriate in elegant ideas, the practical shortcomings of which can be relegated to the category of “mere technical details.” The practical-reactor designer must live with these same technical details. Although recalcitrant and awkward, they must be solved and cannot be put off until tomorrow. Their solutions require man power, time, and money.

Unfortunately for those who must make far-reaching decisions without the benefit of an intimate knowledge of reactor technology and unfortunately for the interested public, it is much easier to get the academic side of an issue than the practical side. For a large part those involved with the academic reactors have more inclination and time to present their ideas in reports and orally to those who will listen. Since they are innocently unaware of the real but hidden difficulties of their plans, they speak with great facility and confidence. Those involved with practical reactors, humbled by their experiences, speak less and worry more.

Deterrence is a game where a big enough mistake kills hundreds of millions if not billions of people

Saturday, August 26th, 2023

Putin’s War in Ukraine is a fairly clear example of the stability-instability paradox:

In a pre-nuclear world, an intervention like this would have risked a direct, conventional response from NATO; at least at the moment it seems clear that the political will for such an intervention exists and is only really restrained by escalation concerns. Consequently, while in a pre-nuclear world invading Ukraine would pose the real risk of sparking an unwinnable conventional war with NATO, in a nuclear world, the Russian Federation can remain relatively sure that the war in Ukraine will remain ‘cabined’ to Ukraine. Moreover, the fact that Russia has nuclear weapons and Ukraine does not means that in the event that Ukraine wins, their ability to exploit that victory would be extremely limited; they could not, for instance, push deeply into Russian territory without triggering a potentially nuclear Russian response. The invasion thus seemed ‘safe.’

More broadly, I think Beaufre’s thinking is actually quite applicable here. Putin’s invasion of Ukraine is a classic interior maneuver and the Russian plan of operations follows Beaufre’s thinking closely: rapid advances with airborne, armor and mechanized forces to try to produce a coup de main that would topple the government and present its replacement as a fait accompli before the rest of the world could react. Clearly that’s not the only thing motivating the Russian operational concept – there seems to have been quite a lot of self-delusion and wishful thinking about how welcoming the Ukrainians would be. That said, it seems fairly clear that the Russian operational plan was designed to try to produce that fait accompli in just a few days, but of course the problem with such lightning advances is that should something go wrong, it is likely to go very wrong, with units spread out and often deep into enemy territory with fewer forces holding rear areas. By contrast, for instance, the United States, far more confident in its exterior maneuvers creating the window of freedom of action to intervene, was able to adopt a fairly methodical approach to the 2003 invasion of Iraq.

Which goes to the next point: Russian exterior maneuvers prior to the invasion were also fairly obvious. The Russian Federation, while building up claimed it had no plans to invade and used ‘exercises’ as a pretense in an effort, one assumes, to maximize confusion in the event and thus make unified action by the rest of the world more difficult. At the same time, Russia attempted to orchestrate a number of false-flag attacks and other fake ‘provocations’ in order to justify their intervention. What is also fairly obvious is that those exterior maneuvers failed, in particular because they lacked any kind of credibility. The smokescreen only works if a meaningful proportion of people believe it. The strategy NATO intelligence agencies took, of ‘calling’ Russia’s shots in advance robbed the strategy of much of its power. Again, the exterior maneuver is all about perception: Russia needed to create a ‘grey-zone’ of acceptability for what it was doing and largely failed.

[…]

The logic of deterrence — in particular the fact that it is both very high stakes and also based entirely on perception — explains why NATO and especially the United States took any direct military action off of the table quite loudly well before the conflict began. Saying that ‘all options are on the table’ — as the United States routinely does with Taiwan — would have been a fairly obvious bluff. When Putin called that obvious bluff, it would have damaged the credibility and thus the deterrence value of that same statement when applied to NATO members or Taiwan, weakening the effect of US deterrence, and thus potentially encouraging another state (like China) to try to call an American bluff elsewhere (essentially inviting a piecemeal maneuver). And of course the danger to that is two-fold: on the one hand if the United States and NATO folds, it calls into question even more of its security arrangements, but if it doesn’t fold, the result is likely to be a major war which in turn could (and frankly probably would) lead to an escalatory spiral ending in the use of nuclear weapons.

Remember: deterrence is a game where a big enough mistake kills hundreds of millions if not billions of people.

[…]

At the same time basically everything that NATO is doing in Ukraine can be understood as having a dual purpose: both attempting to degrade Russian military capabilities (by sinking the Russian economy and arming Ukraine) but also as an exterior maneuver designed to alter the freedom of action of other players in the system. Unable to directly act against Russia due to the concerns of deterrence and escalation, NATO is seeking to close the window of freedom of action tight enough that wars of conquest sit outside of it. It is doing this by rallying world opinion to the imposition of massive economic costs, in an effort to signal that wars of conquest will have such tremendous negative repercussions (even if they don’t trigger direct intervention) as to never be worth the cost.

Nuclear deterrence need not be the end of war by nuclear powers

Friday, August 25th, 2023

In An Introduction to Strategy (1965), French general André Beaufre describes the indirect strategy:

In essence, this sort of strategy is the answer to how two nuclear powers can still compete with each other without triggering a nuclear war. It is, “the art of making the best use of the limited area of freedom of action left us by the deterrent effect of the existence of nuclear weapons.”

When I explain this to my students, I explain it in a spatial metaphor. Imagine two countries (let’s use the USA and the USSR for simplicity), both with nuclear weapons. They each have ‘red lines’ where they would use nuclear weapons. Neither country wants a nuclear exchange, so they have to avoid crossing their opponent’s red lines which would trigger that. But below that threshold, you have a window of ‘freedom of action’ — a sort of ‘space’ (really a set of options) — where either power can engage in all sorts of activity, including military activity (typically against third parties, as directly attacking a nuclear power is almost always over the red line). Beaufre’s term for the things you do inside the window of freedom of action to gain direct advantages is ‘interior maneuvers.’ For instance supplying weapons to the Afghan mujaheddin in order to degrade Soviet control of Afghanistan — that’s an interior maneuver. Intervening militarily to topple a government that is aligned with your competitor but who they have no formal obligation to protect — that’s also an interior maneuver.

But those two powers can also engage in activity designed to alter the window itself, to give themselves more freedom of action or their opponents less. Remember that deterrence is all about perception, not hard and fast rules. If you can convince the world (and your opponent) that a third-country regime isn’t worth defending (because it is evil or a pariah state, etc.), you can potentially do more or more extensive interior maneuvers against it without nearing that red line. Alternately — especially in a democracy — if you can convince your own people that a third-country regime is noble and just, you can generate the political will to harden your red line, thus closing down some of the freedom of action of your opponent. This sort of thing is what Beaufre terms the ‘exterior maneuver’ — efforts made not to manipulate the direct theater of competition, but the freedom of action each side has to act in that theater. A broad range of activities fit here, as Beaufre notes — appeals to international law, propaganda with moral and humanitarian bent, threatened indirect intervention, economic retaliation (sanctions), and of course ultimately the threat of direct intervention.

[…]

All of which means that nuclear deterrence need not be the end of war by nuclear powers; indirect strategy exposes a gap in Brodie’s dictum that the only useful purpose a nuclear military can have is to avert wars.

One such method that Beaufre discusses is what he calls the ‘piecemeal maneuver,’ but is often in English referred to as ‘salami tactics’ — including in this absolutely hilarious bit from Yes, Prime Minister, which is also a surprisingly good explanation of the method. The idea is that to make gains while avoiding escalation, a state can break up the gains they would make into a series of smaller actions, each with its own exterior maneuver ‘cover,’ so that it doesn’t rise to the level of triggering nuclear escalation. Putting together several such maneuvers could allow a state to make those gains which had they all been attempted at once, certainly would have triggered such an escalation. Beaufre’s example, unsurprisingly, was Hitler’s piecemeal gains before his last ‘bite’ into Poland triggered WWII.

Beaufre notes that for piecemeal maneuvers to be effective, they have to be presented as fait accompli — accomplished so quickly that anything but nuclear retaliation would arrive too late to do any good and of course nuclear retaliation would be pointless: who is going to destroy the world to save a country that was already lost? Thus Beaufre suggests that the piecemeal maneuver is best accomplished as a series of coups de main accomplished with fast-moving, armored, mechanized, and airborne forces seizing control of the target country or region before anyone really knows what is happening. The attacking power can then present the maneuver as fait accompli and thus the new status quo that everyone has to accommodate; if successful, they have not only made gains but also moved everyone’s red lines, creating more freedom of action for further piecemeal maneuvers.

Avoiding this problem is why NATO is structured the way it is: promising a maximum response for any violation, however slight, of the territory of any member. The idea is to render the entire bloc immune to piecemeal maneuvers by putting all of it behind the red line (or at least letting the USSR think it is all behind the red line). It is also why American forces are often forward deployed in effectively trivial numbers in key areas in the world in what are often referred to as ‘tripwire’ deployments. Those American forces, for instance, in Poland, the Baltics or on the Korean DMZ (and during the Cold War, in West Germany) were not there to win the war; their purpose was, in a brutal sense, to die in its opening moments and thus ensure that the United States was committed, whether it wanted to be or not. And the reason to do that is to signal to both enemies and allies that any incursion into allied territory, no matter how trivial, will cause American deaths and thus incur an American military response. In that way you can shift the red line all of the way forward, obliterating the area of freedom of action, but only for countries where such a commitment is credible (which is going to generally be a fairly small group).

If one side unilaterally disarmed, nuclear weapons would suddenly become useful

Thursday, August 24th, 2023

Nuclear deterrence can be an odd topic to discuss with people outside of the security studies space, Bret Devereaux notes:

As we’ll see, there is a certain inescapable logic to many of the conclusions of deterrence theory, but the conclusions themselves viewed without considering that logic seem absurd (and occasionally are, even with the logic). Nevertheless, outside of those security studies fields at the college level, we generally don’t teach nuclear deterrence theory in school and so while this is actually one of the most studied and theorized concepts in the modern world (note that this doesn’t mean the theory is necessarily correct, but it does mean that a lot of very smart and well informed people have been grappling with these ideas for a while now), in my experience there is a tendency by the general public to assume that they are the first to notice this or that absurd-seeming conclusion. Everyone has an opinion about nuclear weapons, but the gap between having an opinion and having an informed opinion is both massive and rarely spanned.

Or to put it very briefly: Dr. Strangelove is a great movie, but if you only have your deterrence theory from Dr. Strangelove, you are dangerously under-informed (though while we’re here it seems worth noting that the Soviet automated-launch doomsday device of the film mostly actually exists, as a system called Dead Hand in the West and Perimeter in Russia and still in use by Russia. Presumably, since Russian nuclear forces are currently on high alert, Perimeter is active, which should be a chilling thought. I am going to say this several times because it is a fundamental truth about nuclear weapons: if you aren’t at least a bit worried, you aren’t paying attention).

The atomic bomb allowed the US and its allies to maintain parity with the USSR while still demobilizing:

US airbases in Europe put much of the Soviet Union in range of American bombers which could carry nuclear weapons, which served to ‘balance’ the conventional disparity. It’s important to keep in mind also that nuclear weapons emerged in the context where ‘strategic’ urban bombing had been extensively normalized during the Second World War; the idea that the next major war would include the destruction of cities from the air wasn’t quite as shocking to them as it was to us — indeed, it was assumed. Consequently, planners in the US military went about planning how they would use nuclear weapons on the battlefield (and beyond it) should a war with a non-nuclear Soviet Union occur.

In 1946, three years before the USSR successfully tested its first nuclear weapon in 1949, Bernard Brodie published The Absolute Weapon, which set out the basic outlines of deterrence theory:

  1. The power of a nuclear bomb is such that any city can be destroyed by less than ten bombs.
  2. No adequate defense against the bomb exists and the possibilities of such are very unlikely.
  3. Nuclear weapons will motivate the development of newer, longer range and harder to stop delivery systems.
  4. Superiority in the air is not going to be enough to stop sufficient nuclear weapons getting through.
  5. Superiority in nuclear arms also cannot guarantee meaningful strategic superiority. It does not matter that you had more bombs if all of your cities are rubble.
  6. Within five to ten years (of 1946), other powers will have nuclear weapons. [Of course this happened in just three years.]

Brodie concludes:

Thus, the first and most vital step in any American security program for the age of atomic bombs is to take measures to guarantee to ourselves in case of attack the possibility of retaliation in kind. The writer in making that statement is not for the moment concerned about who will win the next war in which atomic bombs are used. Thus far the chief purpose of our military establishment has been to win wars. From now on its chief purpose must be to avert them. It can have almost no other useful purpose.

By 1959, both the USA and the USSR had mounted nuclear warheads on intercontinental ballistic missiles (ICBMs), which had effectively infinite range and were effectively impossible to intercept.

In The Delicate Balance of Terror (1958), Wohlstetter argued that deterrence was in fact fragile:

Any development which allowed one party to break the other’s nuclear strike capability (e.g. the ability to deliver your strike so powerfully that the enemy’s retaliation was impossible) would encourage that power to strike in the window of vulnerability.

[…]

Like Brodie, Wohlstetter concluded that the only way to avoid being the victim of a nuclear first strike (that having the enemy hit you with their nukes) was being able to credibly deliver a second strike.

[…]

This is the logic behind the otherwise preposterously large nuclear arsenals of the United States and the Russian Federation (inherited from the USSR). In order to sustain your nuclear deterrent, you need more weapons than you would need in the event because you are planning for scenarios in which some large number of weapons are lost in the enemy’s first strike. At the same time, as you overbuild nuclear weapons to counter this, you both look more like you are planning a first strike and your opponent has to estimate that a larger portion of their nuclear arsenal may be destroyed in that (theoretical) first strike, which means they too need more missile[…]

If one side unilaterally disarmed, nuclear weapons would suddenly become useful — if only one side has them, well, they are the “absolute” weapon, able to make up for essentially any deficiency in conventional strength — and once useful, they would be used. Humanity has never once developed a useful weapon they would not use in extremis; and war is the land of in extremis.

Because different kinds of systems would have different survivability capabilities, it also led to procurement focused on a nuclear ‘triad’ with nuclear systems split between land-based ICBMs in hardened silos, forward-deployed long-range bombers operating from bases in Europe and nuclear-armed missiles launched from submarines which could lurk off an enemy coast undetected. The idea here is that with a triad it would be impossible for an enemy to assure themselves that they could neutralize all of these systems, which assures the second strike, which assures the destruction, which deters the nuclear war you don’t want to have in the first place.

Hitler had to decide between two alternatives

How Hitler Could Have Won World War II by Bevin AlexanderWith America’s entry into the war, Hitler had to decide between continuing the attack on the Soviet Union or going on the defensive there, Bevin Alexander explains (in How Hitler Could Have Won World War II), and keeping American and British forces away from the continent of Europe:

For Admiral Erich Raeder, the choice was easy. On February 13, 1942, he proposed that Germany’s primary military tasks should be for Rommel to drive through Egypt to the Middle East, while the army in Russia did only two things: capture Murmansk and close that ice-free port to Allied convoys, and drive into the Caucasus to seize Soviet oil wells. After that the way would be clear to cross into Iran, close off that supply line to Russia, and join up with Rommel. Meanwhile, German war production should be shifted over predominately to the navy and air force to build more submarines and other vessels and aircraft to interdict the flow of supplies from America.

Hitler made it clear that he wanted first to destroy the Red Army and eliminate its sources of strength:

After that, other courses might be followed. But for now, the Ostheer — or army in the east — was to receive priority, and the German economy was to be directed at rearming this army, not at building a great U-boat fleet and air force, and not at reinforcing Rommel.

Weak states come to depend on strong states and, in the process, become client states

Tuesday, August 22nd, 2023

French President Emmanuel Macron has been attempting a large-scale “reset” or “refoundation” of relations with Africa and has explained that “there is no longer a French policy for Africa”:

In August 2020, the military of Mali overthrew the government in a coup d’etat. Since then, in quick succession, four of Mali’s regional neighbors have experienced coup attempts, including successful ones in Guinea and Burkina Faso. The Central African Republic, meanwhile, has become a client state of Russia.2 This unprecedented wave of coups is a consequence of decisions made in Paris to pull back long-standing French troop deployments in French-speaking Africa.

The French military has been actively deployed to West Africa since January 2013, when an offensive was launched to defeat armed separatists in northern Mali who threatened to overthrow the government. Initially successful, the deployment was formalized as Operation Barkhane in 2014 and expanded to neighboring countries, including Niger, Burkina Faso, and Chad. At its peak, Operation Barkhane involved 5500 French soldiers. A United Nations follow-on peacekeeping mission involved about 15,000 UN peacekeepers, including over one thousand German soldiers.

In early 2020, the French government loosened its commitment to military involvement in the region. French President Emmanuel Macron, newly elected in 2017, was unwilling to send more French troops to Africa to bring an end to the ongoing insurgencies, which had multiplied rather than subsided. Macron believed that France’s relationship to Africa needed a “reset” or “refoundation” from its colonial past and, as part of that, France should allow African countries to solve their own problems. French military intervention, therefore, would be scaled back.

[…]

Although formal French colonialism ended in the decades after World War II, France nevertheless maintained a notable sphere of influence in its former African colonies, especially in West Africa. This informal empire was maintained through elite social and business ties with France, as well as through the large-scale involvement of the French military, which was deliberately designed to be capable of rapid intervention in Africa.

[…]

Weak states that cannot suppress insurgencies or alleviate privation on their own necessarily come to depend on strong states and, in the process, become client states. If France will not provide this support, perhaps the U.S. or Russia will.

Their electronic warfare systems weren’t very agile, they weren’t very fast, and they weren’t very numerous

Saturday, August 19th, 2023

In the early days of the invasion of Ukraine, experts were surprised at how poorly the Russian army’s electronic warfare units performed:

Expecting a walkover, Moscow may have thought they wouldn’t need to fully deploy electronic warfare systems. But Bryan Clark, a senior fellow at Hudson Institute, a US think tank, says another problem was that electronic warfare units couldn’t keep up with the rest of the troops.

“Russian systems are large unwieldy, vehicle-borne systems that are designed to be on the defensive,” he says. “And as a result, their electronic warfare systems weren’t very agile, they weren’t very fast and they weren’t very numerous.”

But Russia has learned from its mistakes, he says. Instead of using large equipment that can be easily spotted and destroyed, it is now increasingly relying on smaller, more mobile devices.

Bryan Clark says Russia has managed to deploy hundreds of mobile electronic warfare units along the front line in an attempt to slow down Ukraine’s counter-offensive. These range from GPS jammers to systems that suppress radar and prevent US aircraft identifying targets for Ukraine to attack.

Russian systems such as Zhitel and Pole-21 are proving to be particularly effective to jam GPS and other satellite links. They can disable drones that direct artillery fire and carry out kamikaze attacks on Russian troops.

Many of the sophisticated weapons provided to Ukraine by Nato countries are vulnerable to such jamming too because they use a GPS signal for navigation.

“Zhitel can jam a GPS signal within 30km of the jammer,” says Mr Clark. “For weapons like [US-made] JDAM bombs, which use just a GPS receiver to guide it to the target, that’s sufficient to lose its geolocation and go off target.”

The same applies to the guided rockets fired by the Himars multiple rocket system, which made a big contribution to Ukraine’s successful offensives last autumn.

Oh, yes, we’re expecting Dmitri! Send him on up!

Friday, August 18th, 2023

I was watching Declassified — Season 3, Episode 5, “The Spy Game: Russian Espionage” — on Max, when it explained how the Russians took advantage of the US State Department’s naïve openness right after the fall of the Soviet Union.

State decided to allow Russians in, unescorted, to the building, so one Russian intelligence operative would come into the lobby and wait in one of the lounges outside the security checkpoint. Later, another intelligence operative would come in and present himself to the receptionist with a phone extension to call to confirm that he was welcome to come through.

That phone extension belonged to the phone in the waiting area lounge. “Oh, yes, we’re expecting Dmitri! Send him on up!”

In the desert, surrounded motorized forces nearly always could mass at a single point and break out

Wednesday, August 16th, 2023

How Hitler Could Have Won World War II by Bevin AlexanderRommel had learned something the British had not grasped about desert warfare, Bevin Alexander explains (in How Hitler Could Have Won World War II), that attrition or wearing down of an enemy force and destruction of the enemy’s organic cohesion had to be the tactical aims:

In other environments where few units were mechanized, like Poland in 1939 and western Europe in 1940, the greatest danger a force could face was being surrounded. When encircled, and subjected to fire from all sides, a force tended to disintegrate, and could be destroyed or forced to surrender.

In the desert, surrounded motorized forces nearly always could mass at a single point and break out, thereby nullifying what elsewhere would be a devastating trap.

Rommel accordingly concentrated on winning battles of attrition and shattering the enemy’s organization. He came up with a five-point method of doing this. A commander, he wrote, must (1) concentrate his forces, while trying to split the enemy forces and destroy them at different times; (2) protect his supply lines, while cutting the enemy’s; (3) attack enemy armor with antitank guns, reserving his own tanks for the final blow; (4) operate near the front so as to make immediate decisions when tactical conditions change; (5) achieve surprise, maintain great speed of movement, and overrun disorganized enemy formations without delay. Speed is everything, Rommel wrote. And, after dislocating the enemy, he must be pursued at once and never be allowed to reorganize.

Rommel had only one “secret” weapon, the 88-millimeter antiaircraft (AA) gun that he and other German generals discovered in the 1940 campaign could blast through 83 millimeters of armor at 2,000 yards. This made the 88 the most formidable antitank weapon on either side. The British had a comparable high-velocity AA gun of about the same caliber (3.7 inches), which could have been as effective, but they did not use it against tanks.

Rommel also had the 50-millimeter antitank (AT) gun, which slowly replaced the poor 37-millimeter gun developed before the war. The 50-millimeter gun could penetrate 50 millimeters of armor at 1,000 yards. Although the Matilda with its heavy frontal armor was largely invulnerable to this gun, the more lightly armored cruisers could often be stopped, especially at close range. Both the 88 and the 50-millimeter AT gun could fire solid shot, to cut through armor, or high explosive, which could destroy or neutralize British AT weapons or crews.

By comparison, the British two-pounder (40-millimeter) AT gun was ineffective. It fired only solid shot, requiring a direct hit to destroy enemy AT weapons, and could penetrate merely the thinner side plates of armor at ranges below 200 yards. The British 25-pounder (87-millimeter) gun-howitzer, a superb field artillery piece, had to be pressed into service as an antitank weapon, though often at the expense of protecting infantry. Only in the spring of 1942 did the British begin to receive the six-pounder (57-millimeter) AT gun, which fired high-explosive as well as solid shot and had 30 percent greater penetration than the German 50-millimeter gun.

The British took a long time recognizing that Rommel was sending antitank guns against their tanks. In offensive or attack situations, Rommel leapfrogged the comparatively nimble 50-millimeter AT guns from one shielded vantage point to another, while keeping his tanks stationary and below the horizon. Once the AT guns were established, they protected the tanks as they swept forward.

In defensive situations, Rommel tried to bait or lure the British. He sent light tanks forward to contact the enemy, then retire. The typical British response was to mount a “cavalry” charge. But since visibility was obscured by stirred up dust and sand, British tankers usually did not see the 50-millimeter AT guns waiting in ambush in hollows and draws, nor the “gun line” of 88s drawn up at the rear. The 50s picked off British tanks that got within range, while the 88s took on the advancing enemy armor at distances far beyond the capacity of the tanks’ two-pounder (40-millimeter) guns to respond. The British added to the success of Rommel’s tactics by usually committing their armor piecemeal, mostly single units, instead of full brigades, and never massed brigades.

[…]

The British dispersed their tanks because it was impossible to conceal armor in the desert from the air. Rommel tried to practice the opposite policy, drawing together every possible tank and gun to work against a single objective—which, because of British dispersion, was often a fragment of total British armored strength.

Finally, the British failed to copy the Stuka dive-bomber, which was in effect mobile artillery that could deliver fire on the point a forward force wished to destroy, or through which it wished to advance. The dive-bomber offered the vanguard of an attacking force a way to eliminate an enemy strongpoint shortly after its discovery without having to bring up more weapons.

[…]

Consequently Rommel repeatedly caught British armor dispersed. As he remarked to a captured British officer after the battle: “What difference does it make if you have two tanks to my one, when you spread them out and let me smash them in detail?”

The enemy, the size of the country, and the foulness of the weather were all grossly underestimated

Wednesday, August 9th, 2023

How Hitler Could Have Won World War II by Bevin AlexanderHitler’s greatest strategic mistake, after he’d decided to invade Russia, Bevin Alexander explains (in How Hitler Could Have Won World War II), was his refusal to concentrate on a single, decisive goal:

He sought to gain — all at the same time — three widely distant objectives: Leningrad, because it was the birthplace of Russian Communism; Ukraine and the Caucasus beyond, for its abundant foodstuffs, 60 percent of Soviet industry, and the bulk of the Soviet Union’s oil; and Moscow, because it was the capital of the Soviet Union and its nerve center.

[…]

He hoped to seize a million square miles of the Soviet Union in 1941, a region the size of the United States east of the Mississippi. The campaign in the west, on the other hand, had been fought out in an area of 50,000 square miles, roughly the size of North Carolina or New York State. Therefore, the ratio of space to men was twenty times greater in the east than in the west.

Field Marshal Brauchitsch, commander of the army, and General Halder, chief of staff, wanted the primary objective to be Moscow:

Stalin would be compelled to fight for Moscow. It was the hub of railroads, mecca of world Communism, headquarters of the highly centralized government, and a great industrial center employing more than a million workers.

Moreover, an attack into the center of the Soviet Union would turn the nation’s vastness—generally thought of as its greatest asset—into a liability. Once the Germans possessed Moscow’s communications node, Red Army forces on either side could not coordinate their efforts. One would be cut off from aid and succor to the other, and the Germans in the central position between the two could have defeated each separately.

The German army and economy could support a drive on Moscow. Though 560 miles east of the frontier, it was connected by a paved highway and railroads.

This would have still been a direct, frontal assault against the strength of the Red Army, but the ratio of force to space was so low in Russia that German mechanized forces could always find openings for indirect local advances into the Soviet rear. At the same time the widely spaced cities at which roads and railways converged offered the Germans alternative targets. While threatening one city north and another city south, they could actually strike at a third in between. But the Russians, not knowing which objective the Germans had chosen, would have to defend all three.

Hitler, by trying for too much and then altering his priorities failed everywhere:

These failures meant Germany had lost the war. By December 1941, there was no hope of anything better than a negotiated peace. This Hitler refused to consider.

Hitler’s plan rested on two false assumptions. The first was that he would have time enough (even without the shift of panzers to the Ukraine) to switch armor to the north then back to the center in time to win a decisive victory before the rains and snows of autumn. Distances were simply too great, Russian roads and climate too poor, and Red Army resistance too intense for such a plan to have had any hope of success. As Guderian summarized the campaign to his wife on December 10, 1941, “The enemy, the size of the country, and the foulness of the weather were all grossly underestimated.”
