I thought I was hearing things, but I wasn't. Iran said no to Obama's appeal for help against ISIS:
"We should be grateful for Iran’s intransigence, but very alarmed at
Obama’s attempt at an alliance with Iran, the largest state sponsor of
terror, the backer of Syria’s Bashar al-Assad, the threat to Israel and
Sunni neighbors and the regime determined to get nuclear weapons."
In addition to this, Obama must have a very short memory and obviously doesn't recall the Iranian Hostage Crisis.
