Al Zawahiri dead?
The location of the attack makes a lot of sense. It seems likely that al Zawahiri was in the region as often reported during the winter and as he tries to shift focus from Iraq, where al Qaeda is now hated and despised, to Afghanistan, to try and rally the remaining Taliban . See Bill Roggio for a good analysis.
We'll have to wait for the DNA results (if the bodies have not been moved) to be sure, but I do hope Santa, although with a little delay, has finally delivered one of his presents.
