What do you think of Obama's stance on Iran?

One of the largest criticisms of our current administration by democrats is going to war with Afghanistan and Iraq under the false pretenses of WMD and Saddam's ties to terrorism. Obama says the same thing as Bush when it comes to Iran; that their nuclear program is for military rather than civil application and that Ahmadinejad is a lunatic. Democrats: what do you think of Iran? Why should we continue starting wars?
