On Iraq he seemed to believe that Obama has thrown away everything that had been accomplished there.
A lot of Americans died trying to turn Iraq into a half-way decent country that would not be a danger to its neighbors. Whether that was ever achievable, given Arab Muslim attitudes and traditions, is debatable, but Obama clearly has no interest in making that happen. Rather he needed to please his anti-war base by undoing as much as possible of what Bush accomplished. If the whole intervention in Iraq becomes a total failure, that's probably a positive for Obama and for the Democrats: they can use that to reinforce the theme that it was wrong to get rid of Saddam Hussein.
If a future Iraqi government becomes as big a problem for the US as Saddam was, they won't care and they won't be held accountable. How many Americans blame Jimmy Carter for the current problems in Iran? Without his help, the current gang wouldn't have taken over the country in 1979.
