OK, here goes. My question is, Why the hell is everyone so surprised? Was this not inevitable? Perhaps it was foretold on the day we removed Sunni power from Baghdad, and so took down the bulwark that prevented the westward expansion of Persian power. Certainly it looked likely from the time Maliki decided to attack the Sunni towns to the west of Baghdad.

Is this what American troops were fighting for? No, John, because they don’t get to decide what they are fighting for.

You want a lesson of Iraq? Here’s one: Don’t go invading countries about which you don’t know enough to know what you want to do once you get there.

Ready for another? OK, here: Don’t destroy a power without considering what will fill the ensuing vacuum.
