DONALD TRUMP: Now look, we are going to get rid of [the Islamic State], big league. And we're going to get rid of 'em fast. And we're going to use surrounding states. We're going to use NATO, probably. And we're going to declare war. It is war. When the World Trade Center comes tumbling down, with thousands of people being killed, people are still — I have friends that are still —

LESLEY STAHL: But we did go to war, if you remember. We went to Iraq.

TRUMP: Yeah, you went to Iraq, but that was handled so badly. And that was a war, by the way, that was a war that we shouldn't have entered because Iraq did not knock down — excuse me...

STAHL: Your running mate —

TRUMP: Iraq did not —

STAHL: — voted for it.

TRUMP: I don't care.
