Further into the editorial, he says:
Bush and Blair and many people called neoconservatives believe that moral objectives in politics are universally applicable imperatives. If so, then either national cultures do not significantly differ; or they do not matter; or they are infinitely malleable under the touch of enlightened reformers. But all three propositions are false, and antithetical to all that conservatism teaches about the importance of cultural inertia and historical circumstances.
And he wraps it up with:
The premise that terrorism thrives where democracy doesn't may seem to generate a duty to universalize democracy. But it is axiomatic that one cannot have a duty to do something that cannot be done.
