It was, as the hero tells it, his Road to Damascus moment. There he is, in a hall of 1,500 people he has long considered to be his allies, hearing the speaker treat the Iraq war, nearing the end of its first year, as "a virtually unqualified success." He gasps as the audience enthusiastically applauds. Aghast to discover himself in a sea of comrades so deluded by ideology as to have lost touch with reality, he decides he can no longer be one of them.

And thus did Francis Fukuyama become the world's most celebrated ex-neoconservative . . .

I happen to know something about this story, as I was the speaker whose 2004 Irving Kristol lecture to the American Enterprise Institute Fukuyama has now brought to prominence. I can therefore testify that Fukuyama's claim that I attributed "virtually unqualified success" to the war is a fabrication.

A convenient fabrication -- it gives him a foil and the story drama -- but a foolish one because it can be checked. . . .

Fukuyama now says that he had secretly opposed the Iraq war before it was launched. An unusual and convenient reticence, notes Irwin Stelzer, editor of "The Neocon Reader," for such an inveterate pamphleteer, letter writer and essayist. After public opinion had turned against the war, Fukuyama then courageously came out against it. He has every right to change his mind at his convenience. He has no right to change what I said.
