I'm just thinking out loud here and I might be wrong. What if the terrorists are actually fighting a geurilla war? They try to strike "high impact" targets w/ a small force (sounds like our special forces) and hit the larger superior enemy at his weakest. If we think, "what would I do if I were in their shoes," things kind of make sense. They hit the WTC before. They finished the job this time. There were all kinds of hints that they would do this again. They hit our embassy in Kenya. They hit the U.S.S. Cole while we DID NOTHING. This was not a surprise attack. It's like people acting shocked at the NASDAQ crash. Was it really going to end any other way? If you were a terrorist, what would you go after? Major landmarks, and centers of government. WTC and the Pentagon (possibly the white house). I think there is a very clear logic to their methods. Just my .02.
