“There has never been an American army as violent and murderous as the one in Iraq”

War? What is this "war" of which you speak? I don't recall anyone declaring war. Even if we had, the enemy military has been smashed and their leader deposed. The "war" part of the proceedings is over. Has been for years.

What we are doing now is police/counterinsurgency work. The sooner the Iraqi government is able to take over this work, the better.
