If there is US troop movement within Pakistan, no doubt it will be kept secret and out of media's view. We'd have to crush them if a revolt broke out in Pakistan. That is one thing Bush managed to do that Clinton ignored; He managed to create a dialog and military co-operation with Pakistan. If that falls apart, we don't have many options,
There is too much at risk. Good thing Bush also has good relations with India, we might need them if all H*ll breaks loose.
Maybe it is CIA people more than the military.
Just my impression.
