Iran was the first country to send aid to Iraq’s Maliki government as the Islamic State of Iraq and Syria (ISIS) began to sweep through the nation’s west and drew close to Baghdad. The Iranian Quds Force commander is coordinating the defense of Baghdad.
The Obama Administration has raised the prospect of similarly aiding the Maliki government, likely with air strikes, and Iranian President Hassan Rouhani proposed a joint operation to save their mutual ally from the ISIS takeover.
The Pentagon has long blamed Iran for everything that has gone wrong with Iraq, particularly during the long US occupation, and even though that narrative no longer flies in the face of the growing sectarian war, it seems the mistrust remains. The Pentagon is adamant on this, though the State Department is said to be more open to the idea.
