In an important article at The Weekly Standard, Robert Kagan more or less admits, without explicitly saying so, that Harvard professor Samuel Huntington was right with his famous “clash of civilizations” thesis.

The thesis stands in opposition to the neoconservative belief that all men are the same in their desire for freedom as we know it, and that history is ending with the inevitable advance of liberal democracy. This is major, and it has implications for the neoconservative view of immigration as well.
