The scenarios I've seen talk of limited nukes hitting cities close to the border. Sorry, but I see new Dehli and Islamabad as much more likely targets. City Populations: New Delhi - 11,680,000 (2000 estimate, Source: United Nations Population Division, 1996) Islamabad: 5,800,000 (source unknown).
This would indeed be ugly. I'm surprised the numbers aren't much higher.
It is also clear that there is little that we can do except urge these countries to think clearly, and otherwise wring our hands.
Imagine upwards of 15 million people gone in a matter of minutes. I hope these two nations give this a lot of thought.
