As far as the day after the Libya attack, and Dear Leaders speech in the Rose Garden, he did not use the word "terrorism," but he did use the general term (not attaching it to what had just happened) "act of terror." So he refered to terror, and not terrorism.
Problem is that everyone knows what he was trying to say in the debate, and that is he was trying to convey to the people was that he did call it an act of terror, or terrorism, which he did not. It's a bunch of legal speak. If Dear Leader presses that, he's going to come away looking like Clinton when he said "It depends upon what the definition of 'is' is."
