Wars are generally fought by ordinary folks (mainly men) who don't want to kill other ordinary folk but are compelled to do so by jingoistic politicians or religious leaders who are following their own agenda. The only losers in war are ordinary people, those who cause the wars in most cases are unaffected by them though I acknowledge Hitler and Mussolini didn't fare well. It's all about cannon fodder, the masses are expendable. especially if you have an almost unlimited supply like China or Russia. From a planetary perspective, the big carbon footprint aside, wars are good for winnowing the population, alongside Covid and other global disasters. The bottom line is that war is good for the planet although not for human kind. I'm waffling again, time for some more Leonard Cohen, Closing Time, the Johnny Walker wisdom's running high.
