Then came WWI.
Europe has been in decline ever since 1914. Like Britain after the Roman legions left, I think there will be centuries of darkness before Europe ever matters again.
If they don't come around soon, I fear you are right. My biggest worry is the Left in our own country is following in their footsteps. And this is what will happen in America if the Dems come to power. The anti-war/anti-moral crowd would deny that they are guilty of relativism. Activists and protestors can't possibly be guilty of such a thing, can they? What they don't realize is that they are fighting against is anti-relativism. They are afraid for America to be "right" or moral about international affairs if being right makes us different or unloved.
As the writer points out, it is not America that has changed, it is Europe.
