I'm currently reading "The Strongest Tribe" by Bing West. It appears that the main problem is that the Maliki Govt. being made up of Shiites, will not accept Sunni's in the Police, therefore the police are heavily infiltrated by the Shiite militia Jaish al Mahdi. That is what the US officer is referring to.
What the situation is now I don't know, but basically our war is over, , we are just trying to support the Iraqi's until their own Govt. quits cutting up the spoils and starts supporting the Army and HONEST Police.
Most likely after we leave the Shiites will attempt to wipe out the Sunni's. But the Sunni's are organized now, the same tribes who broke the back of Al Queda in Iraq will stand up to oppression by the Shiites.
Runstowin, You need to understand that profanity is a tool used to convey a lack of respect. Listen to what he is saying, they are not just "cowards" they are "f&%$ing cowards" "women" "dogs". If they want to be treated with respect, treated like "men" they have to act like it. They have to earn that respect.
