“But this -- we got a leader in Iran who has announced that he wants to destroy Israel. I've told people that if you're interested in avoiding World War III, it seems like you ought to be interested in preventing them from have the knowledge necessary to make a nuclear weapon. I take the threat of Iran with a nuclear weapon very seriously.”
Bush was probably referring to Pooty Poot when he said "people." If you watch his press conference and take it all in context, he's not really advocating for WWIII, but all that anyone (the media) got out of his statement, which was ad libbed, was "WWIII and Iran" in the same statement. The war president has really got to give it a rest.
