If India and Pakistan disagree to disagree and the missiles begin flying is there anyplace to flee? Whole divisions of their armies will be vanished, vaporized. It is not only combatants that will face death from the sky. Ten million souls will met their end within a half an hour. Some twenty millions more will be sickened by its power. A cloud of ash will rise above and block the sun from shining. Winter will be premature and soon the crops are dying. A quarter of the human race dead of famine and disease. Please fellows, put your toys away I beg you from my knees.
The opportunities for reincarnation would be severely limited in this scenario, not to mention the dearth of available houri.
