Clinton explains her vote in favor of the Kyl-Lieberman bill naming the Iranian Revolutionary Guard a terrorist organization as simply a vote in favor of economic sanctions against Iran. She says, "I prefer vigorous diplomacy and I happen to think that economic sanctions are a part of diplomacy." Chris Dodd takes the bait and criticizes her for not learning from the buildup to Iraq. Of Kyl-Lieberman he says, "That was a critical moment, and the wrong decision was made." Joe Biden suggests that because of that vote, the price of oil went up and President Bush was emboldened to use "World War III" language. --Dana Goldstein
