The World Is Returning to Normal
If we accept that war, and the preparation for war, is the basic leitmotif of human history, we might also overcome the parallel myth: that all men are basically the same, and all men want the same (good) things. Not so. Just ask Vladimir Putin, Ali Khamenei, and their friends, proxies, and agents. They want bad things for us, namely death and domination. And they're not likely to change, which is why it's very dangerous to give Khamenei more money, and try to make Putin more "reasonable." They're going to continue the war.
"Man is more inclined to do evil than to do good," Machiavelli wrote, and he knew whereof he spoke. Which is why war is normal, and peace so rare. And why we'd better get used to it.
That happy time is done and gone, at least for now. We'd better stop whining and get about the business of winning.
