Pakistan moves

It's impossible to tell what this means as yet, but there are multiple reports that Pakistan has put its military on alert

Pakistan's military called back troops on leave and placed all personnel on active duty Friday, military sources said.

and is shifting its armed forces from the Afghanistan bordering tribal lands, east towards the Indian border.

Pakistan began moving thousands of troops away from the Afghan border toward India on Friday amid tensions following the Mumbai attacks, intelligence officials said.

This is most likely posturing, and there has also been the suspicion that the Pakistanis would use this "crisis" as an excuse to free themselves from trying to police the tribal lands.

However, the counter case that this could be more significant would be that the Pakistanis probably have pretty good spying on India.

My money is on number one, but any increase in tension along that border could be dangerous.

Later: US response. Skeptical that this is anything more than a message to India.
