Vietnam never had a legitimate government in Saigon that 
    the people believed in and trusted. There was superpower 
    engagement in a huge way. [In Iraq] we [have] a problem 
    with the Syrians -- but nothing like what the Chinese and 
    Russians were doing for the North Vietnamese. You had 
    basic sanctuary in North Vietnam. The whole situation, I 
    think, was very, very different. 

    And I'd like to point out one additional aspect. When we 
    left Vietnam, there wasn't a fear that the Vietnamese 
    would come after us. If we fail in Iraq, it will be 
    cataclysmic. You'll see factionalization and eventual 
    Muslim extremism and terrorist breeding grounds that 
    would, I believe, pose a direct threat to the security of 
    the United States. And I'm very glad that the American 
    people -- understandably dissatisfied, understandably 
    frustrated -- still, the majority of them don't think we 
    ought to cut and run.
