Unless you intended to be sarcastic, this statement is based upon the flawed assumption that terrorists are actually motivated by who has troops in Iraq. They only say that when the liberal media is around to lap it up....but it's not their real motivation.
Well, if it was Islamofacists, then they're pretty stupid- which I don't think they are. In fact, it would help our cause if it was terrorists. It would tell people like the French (in the words of the late, great Harold Washington), "You can run, but you can't hide".
