Well of course Obama's gonna say that to the AIPAC. He wants all the support he can get. Most politicians move with the general consensus (for the exception of some like Bush), and the bottom line is, most people in America are so war torn from the Iraq War we really don't want to get into another war, especially since we probably won't be able to afford it in the next few years. Personally I think he's just saying it to gain support from others and even if he truely is for a war with Iran, it's gonna be rather hard for him to gain the support he needs to at least continue with it.
