That is a highly unlikely scenario. If India attacks into Pakistan, the Kashmir border would be the worst place to do it. They have historically attacked into the open central plain, cutting Pakistan in half. This plain is excellent tank country. The Kashmir, on the other hand, is heavily defended mountain passes that would negate any military advantages the superior India Army has. It would be extremely costly for them to attack there, a monumentally stupid stragtegic move.
If the Indians do successfully attack Pakistan, and the Pakis feel they're about to be overrun, they have promised to use their nukes. Under such circumstances, they would likely do so.
Thanks for explaining that. I thought the border buildup meant they were going to go after the terrorists. I figured it was part of "the plan" that we keep hearing so much about.
BTW, there was some speculation of what China would do if this war breaks out.

Looks like they plan to have an opportunity within the next six months.
