The senators go on the offensive in support of their respective nominee's Iraq policy at the Center for U.S. Global Engagement conference Tuesday.
Lieberman: "Senator Obama and those who agreed with him were wrong."
McCain "will not make the mistake of forgetting history, or indulging in the illusion that America can turn inward from the problems of the world."
Biden: McCain's strategy is "playing into Al- Qaeda's hands."
"If we're smart we'll move away from the military pre-emption strategy to the military prevention policy Barack Obama has proposed.”
