Christopher Hitchens writes that he has come to one conclusion that “makes me queasy, but cannot be ducked”:

“We”–and our allies–simply have to become more ruthless and more experienced. An unspoken advantage of the current awful strife in Iraq and Afghanistan is that it is training tens of thousands of our young officers and soldiers to fight on the worst imaginable terrain, and gradually to learn how to confront, infiltrate, “turn,” isolate and kill the worst imaginable enemy. These are faculties that we shall be needing in the future. It is a shame that we have to expend our talent in this way, but it was far worse five years and one day ago, when the enemy knew that there was a war in progress, and was giggling at how easy the attacks would be, and “we” did not even know that hostilities had commenced.
