The most amusing moment of the debate, for me, was hearing the vice president sing the virtues of multilateralism:

IFILL: Mr. Vice President, in June of 2000 when you were still CEO of Halliburton, you said that U.S. businesses should be allowed to do business with Iran because, quote, "Unilateral sanctions almost never work." ...do you still believe that we should lift sanctions on Iran?

CHENEY: No, I do not. And, Gwen, at the time, I was talking specifically about this question of unilateral sanctions.

What happens when we impose unilateral sanctions is, unless there's a collective effort, then other people move in and take advantage of the situation and you don't have any impact...

You said it, mate.
