The border between India and Pakistan has seen a bloody partition in 1947 that killed hundreds of thousands; more than 15,000 dead in three wars and 25 years spent fighting over a glacier; 40,000-100,000 dead (depending on whom you believe) in the insurgency in the disputed province of Kashmir. And now both countries are armed with nuclear weapons.
Bloodshed over the border is not the only measure of the damage this poisoned relationship does. In India it exacerbates feuds between Muslims and Hindus. But Pakistan has been worse affected. Fear and hatred of India have distorted its world view and politics (see article). Ignoring this—as the West seems to be doing again—is a terrible mistake, especially because a settlement is not beyond reach.
