If thats the central purpose, an invasion of the U.S. east coast and Europe would have been more fruitful. The brains and the sponsors of Islamic fundamentalism wouldn't put themselves in a position where they need to dodge bullets or become martyrs.
No, but they put themselves in computers and networks of terrorists busted in Iraq and expose themselves in the US and Europe. And when they are raided, we get more connections and sympathizers. Did someone really have to explain this to you?
