It was interesting watching the Afghanistan war review deliberations, this three-month process where Barack Obama did the most thorough foreign policy review ever by a modern American president. Compare that to Libya. For a month he said we weren't going to do anything, then suddenly changed his mind and did it on the fly. My view is that it's not how long or quick you take to make a decision, it's whether you make the right one.

General McChrystal wanted to be on the cover of Rolling Stone.

One of their major initiatives was getting all officers on Facebook. So the question is, why are these people who are there to train the Afghans being pressured to be on Facebook? Again, it sounds benign until you realize that the military's concern isn't the Afghans, it's convincing the American people that we should be in Afghanistan.Soldiers can put up pictures and say "See how happy the Afghans are because of our presence here." It's a way to directly influence the American people using propaganda.

The idea of aerial military surveillance dates back to the Civil War, when both the Union and the Confederacy used hot-air balloons to spy on the other side, tracking troop movements and helping to direct artillery fire.

Afghanistan would have been difficult enough without Iraq. Iraq made it impossible. The argument that had we just focused on Afghanistan we'd now be okay is persuasive, but it omits the fact that we weren't supposed to get involved in nation-building in Afghanistan.

I'm post-cynical on this stuff. I look at the El Salvador model as the glory days: Why don't we just fund the death squads secretly and keep our boys at home? That where I almost am at this point. Clearly the American military has been a force for good for the United States. There's a reason we have a standing military. But there's something to be said for having a much smaller military because then we wouldn't be tempted to get involved in things we shouldn't be getting involved in.

Johnny Apple, a New York Times correspondent, wrote a front-page story saying Afghanistan could be a quagmire and he was mocked and derided. What is certainly true is that all sorts of resources that would have been used in Afghanistan were diverted to Iraq. Would those resources have helped? Almost undoubtedly. Whether or not Afghanistan would be a peaceful nation-state had we not gone into Iraq I doubt. Afghanistan is going to be Afghanistan, no matter how hard we try to make it something else.
