Vice President Joe Biden went on Larry King Live Wednesday night and told the talk-show host that Iraq, a war which Barack Obama has opposed for many years, "could be one of this administration's greatest achievements." Biden said that he thought another terrorist attack, like the one attempted on Christmas Day, is likely. "I think there are going to be attempts," he told King. The vice president also said that what keeps him up at night is not Afghanistan or Iraq but Pakistan. "I think it's a big country. It has nuclear weapons that are able to be deployed. It has a real significant minority of radicalized population," Biden said, adding, "It is not a completely functional democracy in the sense we think about it, and so that's my greatest concern."
