Both Iran and ISIS are Sunni. I doubt if they are going to harm one another.
Wrong. Iran and the majority in Iraq are Shiite. ISIS is Sunni.
ISIS is Sunni, Iran and Syria are Shite. A majority of Iraq is Shite, and the Sunni didn’t like the new gov’t (Shite) which started some of the problems.
Actually Iran is Shia. they would be happy to destroy the ISIS and take over their territory in Iraq and Seria
