The real "D'uh"
The reason they hate us is because we tolerate some Israelii's theft of Palestinian land.
By the way, our media does not even use the right words in their reportage. Bin laden's group is not "al Qaeda"; "The Net" is the name of their operational technique. Their proper name is "The United Front against Crusaders and Jews", by you'll never hear that.
I think it quite likely that they hope to hit us again by November.
