What will be interesting is to see whether the extremists he goes after will finally include the al Qaeda contingent in North Waziristan. For that matter, if he would simply unleash American forces in that area, it would be a great boon.

Going after an extremist population in your own country is one thing, allowing a foreign power to attack your people (even those you're attacking) on your land is quite another. I don't think anything would make Musharraf look weaker or more like a US tool than allowing US forces to cross his border.

I wonder if those radical elements Musharraf's planning on purging would include the ISID, his own intelligence organization, which is the primary backer of the Taliban.

I'm sure he'll get around to that just as soon as the US purges the Iraqi Kurds who are supporting terrorists in Turkey.
