Shouldn't the United States keep the promises we made to the Iraqi people?

To pick up and leave would break the promises we have made to the Iraqi people, would leave hundreds of thousands of innocent civilians defenseless, would lead to mive chaos and bloodshed, and would be an act of moral dishonor. It would be akin to what the Allies did after World War II, when they abandoned Eastern Europe to the Soviets and returned millions of Russian refugees and POWs to lands occupied by the Red Army—even though the Allies knew that, for many, it meant death and, for the rest, tyranny. ---Charles Colson
