Ryan Crocker, former US Ambassador in Iraq, emphasized the worst action for the US is to support Iran and its mercenaries in Iraq. In an interview with CNN he said while Iraqis are involved in forming their government, the worst thing to do is depict such an image that we support Iran and its agents inside Iraq. These measures will completely send the Sunnis in the opposite direction.
Ryan Crocker added when IRGC Quds Force commander Qassem Suleimani has been in Iraq for a very long time it is clear that he is our enemy and we are working with contradicting objectives.
