During the second debate:

KERRY: Well, let me tell you straight up: I've never changed my mind about Iraq. I do believe Saddam Hussein was a threat. I always believed he was a threat. Believed it in 1998 when Clinton was president. I wanted to give Clinton the power to use force if necessary.

Then, about five minutes later, after a question about Iran:

KERRY: I don't think you can just rely on U.N. sanctions, Randee. But you're absolutely correct, it is a threat, it's a huge threat. And what's interesting is, it's a threat that has grown while the president has been preoccupied with Iraq, where there wasn't a threat.
