Some key quotes:

"Of the four principles, three have failed, and the fourth -- democracy promotion -- is hanging by a sliver," said Geoffrey Kemp, a National Security Council staff member in the Reagan administration and now director of regional strategic programs at the Nixon Center.

"There's already been a retreat from the radicalism in Bush administration foreign policy," said Walter Russell Mead, a Council on Foreign Relations senior fellow. "You have a feeling that even Bush isn't saying, 'Hey, that was great. Let's do it again.' "

"Neoconservatism has been replaced by neorealism, even within the Bush White House," Kemp said. "The best evidence is the administration's extraordinary recent reliance on [U.N. Secretary General] Kofi Annan and [U.N. envoy] Lakhdar Brahimi. The neoconservatives are clearly much less credible than they were a year ago."
