McCain now taking his marching orders from OBL?

Matt makes an important point about the lack of logic in the '100 years war' crowd.

McCain is reporting Osama's recent calls on Sunni Arabs to pour into Iraq to fight the Americans placing OBL and "General Petraeus in agreement, and that is, the central battleground in the battle against al Qaeda is in Iraq today."

So what happens if we leave? Al Qaeda losses it great rallying cry to kill Americans conveniently located in their back yard. And this would be terrible because?

Matt's take,

There's no question that, as McCain points out here at some length, that bin Laden would really like to see an epic struggle in Iraq between the United States military and an array of al-Qaeda recruits who, inspired by the idea of a struggle against American occupation, will flood into that country. As McCain says, this is bin Laden's view of how events in the world are unfolding. Why McCain thinks the correct response is to do what bin Laden wants, I couldn't quite say. Possibly, he's just not very bright.

This all seems so obvious to me, and yet, no one seems interested in challenging McCain directly.
