Rubio is a complete ignoramus when it comes for foreign policy. He made that clear at the Conservative Political Action Conference last month. So did Louisiana Gov. Bobby Jindal.

As Daniel Larison of the American Conservative notes, neither of these nutty neocons understands who's fighting whom in the Mideast.

Neither understood the painfully obvious fact that the Shiite Iranians are the most bitter enemies the Sunni Islamic State faces. Rubio went to far as to tell Sean Hannity that "if we wanted to defeat them militarily, we could do it. He [Obama] doesn't want to upset Iran,"

Larison observes that "As others have noted already, this criticism makes absolutely no sense. If Obama didn't want to 'upset' Iran, he would probably be committing the U.S. to do far more against ISIS, since the Iranians loathe ISIS and have been fighting them in Iraq. If ISIS were defeated, it would deprive Iran of a hated regional enemy, so they would hardly be 'upset' by this outcome."
