I learned with some surprise several years ago that some people miss the Cold War. It gave meaning to political reality. We were the Good Guys and they were the Bad Guys. An ancient story.
It also had religious grandeur. Nuclear Armageddon. Nuclear winter. Lingering radioactive death and the dry sands of reproductive sterility and mutant babies. A holy terror that was Biblical in scope. It revitalized Xtian apocalypsism, gave a scientific means for ending the world, and no holocaust has ever loomed so large as the images of atomic bomb explosions that ironically always failed to stop the alien invasions in vintage sci-fi films. (Heaven, perhaps, is only a force field away?)
"What we may be witnessing is not just the end of the Cold War, or the passing of a particular period of post-war history, but the end of history as such: that is, the end point of mankind's ideological evolution and the universalization of Western liberal democracy as the final form of human government." Francis Fukuyama
We're running out of people to hate except ourselves.
