My argument then, as now, was the necessity of this undertaking, never its ensured success. And it was necessary because, as I said, there is not a single, remotely plausible, alternative strategy for attacking the root causes of Sept. 11: "The cauldron of political oppression, religious intolerance, and social ruin in the Arab-Islamic world -- oppression transmuted and deflected by regimes with no legitimacy into virulent, murderous anti-Americanism."
Fukuyamas book is proof of this proposition about the lack of the plausible alternative. The alternative he proposes for the challenges of Sept. 11 -- new international institutions, new forms of foreign aid and sundry other forms of "soft power" -- is a mush of bureaucratic make-work in the face of a raging fire. Even Berman, his sympathetic reviewer, concludes that "neither his old arguments nor his new ones offer much insight into this, the most important problem of all -- the problem of murderous ideologies and how to combat them."
As they say, read the whole thing.
