So it goes. Having left Iraq after the deaths of 4,500 U.S. troops and an incredible $2 trillion spent, we are now heading back to prop up a murderous despot, who has carried out a religious war against his enemies in part by using U.S. arms.

By comparison, the White House staff numbers 1,701 people. As Islamic insurgents are now sweeping down toward Baghdad, we have already begun a partial embassy evacuation, though the State Department prefers to say people are being temporarily relocated. Pentagon spokesman John Kirby has assured us that U.S. military forces have the assets and resources necessary to evacuate our personnel should Baghdad fall. But were not there yet, he said. Yet.
