[T]his is an enemy for life, as well as an enemy of life.

Now is as good a time as ever to revisit the history of the Crusades, or the sorry history of partition in Kashmir, or the woes of the Chechens and Kosovars. But the bombers of Manhattan represent fascism with an Islamic face, and there's no point in any euphemism about it. What they abominate about 'the West,' to put it in a phrase, is not what Western liberals don't like and can't defend about their own system, but what they do like about it and must defend: its emancipated women, its scientific inquiry, its separation of religion from the state. Loose talk about chickens coming home to roost is the moral equivalent of the hateful garbage emitted by Falwell and Robertson, and exhibits about the same intellectual content.

It's often a bad sign when people defend themselves against charges which haven't been made.

It can certainly be misleading to take the attributes of a movement, or the anxieties and contradictions of a moment, and to personalize or 'objectify' them in the figure of one individual. Yet ordinary discourse would be unfeasible without the use of portmanteau terms—like 'Stalinism,' say—just as the most scrupulous insistence on historical forces will often have to concede to the sheer personality of a Napoleon or a Hitler. I thought then, and I think now, that Osama bin Laden was a near-flawless personification of the mentality of a real force: the force of Islamic jihad. And I also thought, and think now, that this force absolutely deserves to be called evil, and that the recent decapitation of its most notorious demagogue and organizer is to be welcomed without reserve. Osama bin Laden's writings and actions constitute a direct negation of human liberty, and vent an undisguised hatred and contempt for life itself.

The United States finds itself with forces of reaction. Do I have to demonstrate this? The Taliban's annihilation of music and culture? The enslavement of women?

Some readers may have noticed an icy little missive from Noam Chomsky ["Letters," December 3], repudiating the very idea that he and I had disagreed on the "roots" of September 11. I rush to agree. Here is what he told his audience at MIT on October 11:

I'll talk about the situation in Afghanistan.... Looks like what's happening is some sort of silent genocide.... It indicates that whatever, what will happen we don't know, but plans are being made and programs implemented on the assumption that they may lead to the death of several million people in the next—in the next couple of weeks.... very casually with no comment.... we are in the midst of apparently trying to murder three or four million people.

Clever of him to have spotted that (his favorite put-down is the preface 'Turning to the facts...') and brave of him to have taken such a lonely position. As he rightly insists, our disagreements are not really political.
