The United States had gone to war, not under enemy attack, nor to protect the lives or property of American citizens. Nor was the action taken in crusading spirit, as in World Wars I and II, to save the world. The American people had entered a war, not by the roaring demand of Congress — which alone could constitutionally declare a state of war — or the public, but by executive action, at the urging of an American proconsul across the sea, to maintain the balance of power across the sea.

This was the kind of order Disraeli might have given, sending Her Majesty’s regiments against the disturbers of Her Majesty’s peace. Or the emperor in Rome might have given such a command to the legions when his governor in Britain sent word the Picts were over the border.

In 1950 there was only one power and one people in the world who could prevent chaos and a new, barbarian tyranny from sweeping the earth. The United States had become a vast world power, like it or not. And liking it or not, Americans would find that if a nation desires to remain a great and moral power there is a game it must play, and some of its people must pay the price.
Truman, sending the divisions into Korea, was trying to emulate the Roman legions and Her Majesty’s regiments — for whether the American people have accepted it or not, there have always been tigers in the world, which can be contained only by force.
But Truman and the American Republic had no legions.

The United States Army, since 1945, had, at the demand of the public, been civilianized. The men in the ranks were enlistees, but these were the new breed of American regular, who, when they took up the soldier, had not even tried to put aside the citizen.
They were normal American youth, no better, no worse than the norm, who though they wore the uniform were mentally, morally, and physically unfit for combat, for orders to go out and die.
They wore the uniform, but they were still civilians at heart.
The ancient legions, and the proud old British regiments, had been filled with taverns’ scum, starvelings, and poor farm boys seeking change. They had been inducted, knocked about, ruled with a rod of iron, made into men of iron, with iron discipline. They were officered by men wholly professional, to whom dying was only a part of their way of life. To these men the service was home, and war — any war — their profession.
These legions of old, like the sword itself, were neither moral nor immoral. Morality depended upon the use to which their government put them. But when put to use, they did not question, did not fail. They marched.
In 1950 America, imperfectly understanding her position in this new world, had no legions. She had even no men in “dirty-shirt blue,” such as had policed the Indian frontier. She had an army of sorts of citizens, who were as conscious of their rights and privileges as of their duties. And she had only a reserve of more citizens to fall back upon.
Citizens fly to defend the homeland, or to crusade. But a frontier cannot be held by citizens, because citizens, in a republic, have better things to do.

The single greatest weakness of a free people is always their moral doubts. Fortunately for the world, in 1950 the men in the United States Government overcame theirs.
