What is moral about demanding even more needless sacrifice of American lives merely to save face with the mistake of invading and occupying Iraq? Doesn't it seem awfully strange that the Iraqi government we support is an ally of the Iranians who are our declared enemies? Are we not now supporting the Iranians by propping up their allies in Iraq? If Maliki is our ally, and he has diplomatic relations with Ahmadinejad, why can't we? … Why should we not expect many of the 80,000 Sunnis we have recently armed to someday turn their weapons against us, since they, as well as the Mahdi Army, detest any and all foreign occupation? … Since no one can define winning the war, just who do we expect to surrender?
