Probably significantly more times than anybody cares to admit. People aren’t exactly nice to each other today, but holy hell the known atrocities of ancient people. Who knows what got omitted or hero washed?
Being a retired soldier my perspective is thus: the winners that are writing the history books aren’t necessarily the winners, but those who killed the most.
Often those who deviate from the laws of war in order to cheat and win in horrific ways then get to write about the other side being the bad guys…
Those cucumber farmers in Iraq sure didn’t seem like the Al-Qaeda/ isis that I was told they were. Afghanistan was similar. Nobody was the hero involved in that.
It worked for Hitler, and the Republican Party seems to be taking straight from his playbook. (“Mein Kampf” means “my struggle” and was written in jail in ~1924 during his 5 years in prison for a failed coup attempt. Trump appears to be trying to speedrun the whole thing.)
In order to stop Nazis you have to stop the ideology of fascism which is unfortunately sorta baked into America’s racist puritanical capitalist genocidal origins. Hitler even took notes from American Jim Crow policies and racist/poisonous border controls. We have to fight this colonialist abusive mindset at all levels, from uncles and stepdads and cops to CEOs, investors, and politicians.
