And now when we hear that Iran and Iraq plan to cooperate more closely and that a fundamentalist is coming to power in Tehran - a man about whom we cannot be sure that he is absolutely averse to terrorism - it is very worrisome.

There is no question that Iraq is one of the main problems. You'd have to be blind not to see what a magnet and generating force it's become for terrorist groups.
