Today is the 100th anniversary of the armistice that ended World War I, which killed something between 15 and 19 million people, an astonishing and colossal waste of human life and potential.
Sometimes it is necessary to engage in violence to prevent even worse violence, but it is always a terrible thing when that happens, and is nothing to be celebrated. At best, the “victory” of the allies was that nothing particularly worse happened, although what happened (including the deaths of about 2% of the population of Great Britain and 4.25% of the population of France) was pretty much as awful as one would imagine to begin with. As an anti-nationalist, I note that there is no good reason to believe the deaths of millions of Austrians and Germans (something like 4% of the population in those countries) was any less of a tragedy. All deaths are tragedies, and all deaths are premature.
War is not glorious. It achieves no great goals. It cures no diseases, it bridges no rivers, it builds no great cities, it does not launch people into space, clothe the naked, or feed the hungry. Those are worth celebrating, those sorts of achievements represent mankind at its best. War does quite the opposite thing — it destroys resources in bulk, kills vast numbers of people, and sets back human achievement, sometimes by years, sometimes by decades or longer.
Nor is participation in war laudable. Sometimes it is necessary to defend oneself, but there is never any glory in it. Dying face down in the mud is tragic, not glorious, and World War I was almost nothing but one tragedy after another, over and over, multiplied by the millions.
So, today is properly a day of mourning, for a world that was happily growing in population, accumulating capital, and engaging in peaceful trade, which was rent asunder by a stupid, useless waste of human life.
At one point, this trauma was deeply etched into the minds of most average people, but the memory has faded as the generations have passed, and thus the world flirts with horror again and again. Humans do learn, but far too slowly, and there are many people who work actively to tell other people things that are not true.
Sadly, intelligence and rationality are not universally revered, and thus, many are forced to learn the same things over and over, with bloody results.
