I just hope the humanists come out of the cracks in the wall soon, otherwise we're in for a rough time.
We're in for it in any case. People don't want to hear that, so far too many simply deny it. But Francis Fukuyama was wrong. We're not at the end of history; we're still very close to the beginning. And it's noisy, and it will stay that way for a while.
As for the current unpleasantness, if it is a real war, and if it's as serious as some think it is, then it will probably last, at a minimum, a bit longer than the Cold War. That is, few reading the news today will be around to see the end of it. That's if it goes well. If it doesn't go well, the 21st and 22nd centuries will likely be a period of even more pervasive warfare than the 20th was. The longer we wait before taking it seriously, the longer the eventual fight will last.
The general parallels with 1939 are alarming. Denial is an overpowering force. Recall that even such a paranoic as Stalin succumbed to it, for a while. A German deserter alerted the Russians to
Barbarossa a few days before its launch, complete down to places and times of the coming attacks. Stalin, who had a unique way of dealing with unwanted news, simply had the man shot.
Barbarossa happened anyway (fine, fine; 1941, not 1939) - a colossal disaster for the Soviet Union, hardly a minor oversight on Uncle Joe's part. Another clear parallel is the unfounded faith in the efficacy of a transnational organization's ability to do anything useful. If the delegates to the League of Nations had ever had any illusions, they should have cleared out their desks and gone home after their failure to do anything at all about Italy's invasions in North Africa. That was supposedly what the League was there for. Failure, total and complete, was its only enduring legacy. Only a Pollyanna would insist that the UN is a useful improvement over the League.
Sometimes, one really must simply pick one's side (an obvious first step, sometimes overlooked), and then fight until one wins. People don't want to hear that, either.
