I (BMcC[18-11-46-503]) think World War I is a better war for studying war than World War II because in World War I the choice between the two opposing sides was relatively indistinguishable: British imperialist capitalism versus German imperialist capitalism. In World War II, the choice was between extermination camps and so-called liberal so-called democracy.
World War I produced World War II by the victors imposing crushing reparations on the loser: Germany. This led to a vengeancocracy: the Nazis getting even. World War I itself, on the other hand, up until the cessation of hostilities on "the Eleventh hour of the Eleventh day of the Eleventh month" of 1918, was just plain imperialist potlatch. Whichever side won it would have been pretty much the same on the Western Front. Also, right up to Augusr 1914, people were even more sentimental than in World War II. Life in the trenches ended the age of songs about young men asexually loving each other; the machine gun ended the romance of Charges of the Light Brigade. War is bad
This morning (+2024.02.26), I am somehow watching a boring, not very high quality but terrifying movie: "FAIL SAFE" (1964). Apparently the same year as Stanley Kubrick's "Dr. Strangelove or: How I Learned to Stop Worrying and Love the Bomb" which seemed to me a good film. Regular Americans actually paid to see this in theaters? According to th Bing AI, not very many, due to Dr. Strangelove having preceded it in the same year.
The Professor Groeteschele character in the movie seems like today's neocons "on steroids": He sees the potential of us accidentally dropping a hydrogen bomb on Russia due to a system failure as an opportunity to launch an all-out war against them and says they will be too cowardly to respond. He calls the Russians: THe Evil Communists who are not human, and on and on he goes.
I found this movie far more frightening than anything else I've seen in the media. Probably because "we", i.e.: The United States and other Western governments, seem to be doing very reckless and foolish things anent Ukraine today, almost like Professor Groeteschele.
