Yeah, how about this scenario
Hardline radical government takes over in Pakistan making claims it will claim the Kashimer province no matter the cost…
India reacts by mobilizing on its Northern border…
At the same time Pakistan mobilizes…
Meanwhile, an unnoticed truck rolls into New Dehli…
In an instant, India’s population is reduced by 10 milllion…
Followed by India lauching a nuke reducing Karachi to ashes….
Nope, I don’t see the familiarity (with the start of WWI) at all…
Good, we're making progress. Let me explain again. Unlike 1914, there are no mutual-aid treaties obligating the superpowers, and other nuclear powers like China, Britain, France, N. Korea - and probably Israel - to enter the fray. There are no large Hindu nations outside India, so there would not even be a religious reason for any country to attack Pakistan in retaliation, and risk getting nuked themselves. This war in far-off Asia would not involve any member nations of Nato, the only similar pact to some of the 1914 ones.
Russia would not give a toss about the loss of 1% of India's population, and would not declare war on Pakistan. (Someone in the Kremlin would probably remark that India adds that number every few months, and in any case disease and malnutrition take off a like number, slowly, every year or two).
The US would be rightly horrified at such an attack, but that is as far as it would go, other than to cut off the hundreds of millions of $ it sends Pakistan each year, which should have been stopped years ago when that country allowed al Qaeda a haven.
India would certainly retaliate, and since it would be clear that al Qaeda was responsible, the whole tribal area where they live and train their operatives would be removed from the map - other than the loss of innocent lives of the local tribesmen, a net gain to the world.
If past history is any guide, the other probability is that the totally useless United Nations would propose a resolution blaming the US and Israel, and the Bush-haters would blame him. Oh, wait. That has already started. Butto's assassination was Bush's, and America's, fault. Example: New Mexico Gov. Bill Richardson, running on the Dem. ticket for president, speaking yesterday about the assassination of Benazir Bhutto, sharply criticized the Bush administration's Pakistan policy and urged him to "force" Musharraf from power. (How? Invade Pakistan? Send a hit squad?)
