Iraq, five years since the invasion

Like most libertarians, I have a knee-jerk reaction against staying in Iraq now. I don't really remember what I thought of invading Iraq back in 2003. I think that I vaguely thought it might be a good idea to take down Saddam Hussein, but I was mostly just accepted that it seemed natural for the U.S. to invade Iraq. The media totally failed. They didn't question the politicians substantively, and they really neglected to ask any of the hard questions.

Anyway, if anyone could convince me that invading Iraq was a good idea and that we must remain there now, it would be Christopher Hitchens.
