This is new to me. the civil war in Iraq in 2004 was caused by iranians and ALquaida who flooded in after the war.

Blair has argued in his autobiography and in a major speech in June 2014 that the bulk of the bloodshed, and the cause of the civil war from 2004 was the decision of both Iran and al-Qaida to enter Iraq, and to destroy the western reconstruction of Iraq. I thought the reason we went to war was because of al-quaida.
