"CHRISTOPHER HITCHENS: Anyone who lost their "innocence" on September 11 was too naïve by far, or too stupid to begin with. On that day, we learned what we ought to have known already, which is that clerical fanaticism means to fight a war which can only have one victor. Afghans, Kurds, Kashmiris, Timorese and many others could have told us this from experience, and for nothing (and did warn us, especially in the person of Ahmad Shah Massoud, leader of Afghanistan's Northern Alliance). Does anyone suppose that an ideology that slaughters and enslaves them will ever be amenable to "us"? The first duty, therefore, is one of solidarity with bin-Ladenism's other victims and targets, from India to Kurdistan.

The second point 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. Come to think of it, perhaps we were a bit "innocent" after all."
