Iran and America Corprorating In Iraq?

Here's a werid hypothedical: The American's and Iranian's joining forces to combat ISIL militants fighting to establish an Islamic Calphate streching from Syria accoss Iraq.   This crisis has drawn together two nations which have had no diplomatic relations since 1979 when Iranian students took control of the American embassy in Terhran and held 54 people hostage for more than a year.

Today, supposided enemies have a shared interst in prevent ISIL from establishing a beachhead in Iraq.    If not for George W. Bush and the complete stupidity of American Neo-Cons Iraq wouldn't currently be decending down the rabbit hole.  While reglious and ethnic divisions would still exist they wouldn't be manifiesting themselves in open warfare.

Iran is ready to assist the Iraqi government in its battle against extremist Sunni insurgents, President Hassan Rouhani has said.

But he denied Iran had sent troops into Iraq to help bolster Iraqi government forces' defences.

The insurgents - from the Islamic State in Iraq and the Levant (ISIS) - have seized the cities of Mosul and Tikrit and are moving closer to Baghdad.

They regard Iraq's Shia majority as "infidels".

Iran has close ties with the Shia-dominated Iraqi leadership which came to power after the toppling of President Saddam Hussein, whose powerbase was the country's Sunni minority.

Rouhani also made reference to the fact Tehran was cooperating with its old enemy Washington to defeat the Sunni insurgent group – which is attempting to ignite a sectarian war beyond Iraq's borders.
The Iraqi official said 1,500 basiji forces had crossed the border into the town of Khanaqin, in Diyala province, in central Iraq on Friday, while another 500 had entered the Badra Jassan area in Wasat province overnight. The Guardian confirmed on Friday that Major General Qassem Suleimani, the head of the Iranian Revolutionary Guards' elite Quds Force, had arrived in Baghdad to oversee the defence of the capital.
