Blake Hounsell says to chill:
Zawahiri, who watched his previous organization get destroyed in Egypt during the 1990s, likely understands that the escalating campaign of terrorist bombings in Pakistan will strengthen Musharraf's hand still further. But al Qaeda would enjoy a propaganda bonanza if the U.S. started seriously mucking around in the tribal areas. And then there's the small problem that even the United States likely doesn't **have** the ability to sneak into the tribal wilds of Pakistan with a compact strike force, kill the bad guys, and make a clean getaway without anyone noticing. This ain't the movies. Better to give the Pakistanis the time to do it themselves.
