Iran Khamenei said that he was "really entertained" by US statements of combatting ISIS while in hospital. Again refuses cooperation with US

First of all the whole matter of who invited and who declined is unclear in the Iran – anti ISIS coalition story.

— Thomas Erdbrink (@ThomasErdbrink) September 15, 2014

But what matters is that Iran cannot be a part of a US led coalition, from an ideological perspective.

The Iranians can now sit back, watch the show; if anything goes wrong they can blame the coalition as they have no responsibility themselves

Also, despite what many commentators hoped: US cannot be seen aligning with Shiite Iran as it would alienate deep ties with Arab states.

Iran now in comfortable position, it is the only country which controls boots on the ground and it will make sure to keep influence in Iraq.

— Thomas Erdbrink (@ThomasErdbrink) September 15, 2014

Actually it would really have been a sign of deep, serious political change if Iran had been a part of this coalition.

Iran's Khamenei also said: "some officials did not disagree with discussing cooperation with the US (on ISIS), but I disagreed." #thatsfinal

Illustrating the debate among Iran leaders over US – Iran coop, dep FM Araghchi said today that: "consultations are still taking place."
