Robert Kaplan argues that the greater Middle East comprises several shatter zones:
Like rifts in the Earth’s crust that produce physical instability, there are areas in Eurasia that are more prone to conflict than others. These “shatter zones” threaten to implode, explode, or maintain a fragile equilibrium. And not surprisingly, they fall within that unstable inner core of Eurasia: the greater Middle East, the vast way station between the Mediterranean world and the Indian subcontinent that registers all the primary shifts in global power politics.
The Indian subcontinent is the first such shatter zone he describes:
It is defined on its landward sides by the hard geographic borders of the Himalayas to the north, the Burmese jungle to the east, and the somewhat softer border of the Indus River to the west. Indeed, the border going westward comes in three stages: the Indus; the unruly crags and canyons that push upward to the shaved wastes of Central Asia, home to the Pashtun tribes; and, finally, the granite, snow-mantled massifs of the Hindu Kush, transecting Afghanistan itself. Because these geographic impediments are not contiguous with legal borders, and because barely any of India’s neighbors are functional states, the current political organization of the subcontinent should not be taken for granted. You see this acutely as you walk up to and around any of these land borders, the weakest of which, in my experience, are the official ones — a mere collection of tables where cranky bureaucrats inspect your luggage. Especially in the west, the only border that lives up to the name is the Hindu Kush, making me think that in our own lifetimes the whole semblance of order in Pakistan and southeastern Afghanistan could unravel, and return, in effect, to vague elements of greater India.In Nepal, the government barely controls the countryside where 85 percent of its people live. Despite the aura bequeathed by the Himalayas, nearly half of Nepal’s population lives in the dank and humid lowlands along the barely policed border with India. Driving throughout this region, it appears in many ways indistinguishable from the Ganges plain. If the Maoists now ruling Nepal cannot increase state capacity, the state itself could dissolve.
The same holds true for Bangladesh. Even more so than Nepal, it has no geographic defense to marshal as a state. The view from my window during a recent bus journey was of the same ruler-flat, aquatic landscape of paddy fields and scrub on both sides of the line with India. The border posts are disorganized, ramshackle affairs. This artificial blotch of territory on the Indian subcontinent could metamorphose yet again, amid the gale forces of regional politics, Muslim extremism, and nature itself.
Like Pakistan, no Bangladeshi government, military or civilian, has ever functioned even remotely well. Millions of Bangladeshi refugees have already crossed the border into India illegally. With 150 million people — a population larger than Russia — crammed together at sea level, Bangladesh is vulnerable to the slightest climatic variation, never mind the changes caused by global warming. Simply because of its geography, tens of millions of people in Bangladesh could be inundated with salt water, necessitating the mother of all humanitarian relief efforts. In the process, the state itself could collapse.
Of course, the worst nightmare on the subcontinent is Pakistan, whose dysfunction is directly the result of its utter lack of geographic logic. The Indus should be a border of sorts, but Pakistan sits astride both its banks, just as the fertile and teeming Punjab plain is bisected by the India-Pakistan border. Only the Thar Desert and the swamps to its south act as natural frontiers between Pakistan and India. And though these are formidable barriers, they are insufficient to frame a state composed of disparate, geographically based, ethnic groups — Punjabis, Sindhis, Baluchis, and Pashtuns — for whom Islam has provided insufficient glue to hold them together. All the other groups in Pakistan hate the Punjabis and the army they control, just as the groups in the former Yugoslavia hated the Serbs and the army they controlled. Pakistan’s raison d’être is that it supposedly provides a homeland for subcontinental Muslims, but 154 million of them, almost the same number as the entire population of Pakistan, live over the border in India.
To the west, the crags and canyons of Pakistan’s North-West Frontier Province, bordering Afghanistan, are utterly porous. Of all the times I crossed the Pakistan-Afghanistan border, I never did so legally. In reality, the two countries are inseparable. On both sides live the Pashtuns. The wide belt of territory between the Hindu Kush mountains and the Indus River is really Pashtunistan, an entity that threatens to emerge were Pakistan to fall apart. That would, in turn, lead to the dissolution of Afghanistan.
The Taliban constitute merely the latest incarnation of Pashtun nationalism. Indeed, much of the fighting in Afghanistan today occurs in Pashtunistan: southern and eastern Afghanistan and the tribal areas of Pakistan. The north of Afghanistan, beyond the Hindu Kush, has seen less fighting and is in the midst of reconstruction and the forging of closer links to the former Soviet republics in Central Asia, inhabited by the same ethnic groups that populate northern Afghanistan. Here is the ultimate world of Mackinder, of mountains and men, where the facts of geography are asserted daily, to the chagrin of U.S.-led forces — and of India, whose own destiny and borders are hostage to what plays out in the vicinity of the 20,000-foot wall of the Hindu Kush.
