When I was in school…I’m pretty sure the state history cirriculum was designed to be America centric, and pro-America. Any nation a boomer would remember being at war with? Not in the history books, or they appear out of nowhere, do something pro-America, and then disappear again, like Russia did from 1939 to 1945. And both World and US history classes end at 1950 because 1. to the limp dicks that actually make the policy, “The fifties are practically now” and 2. we haven’t done much “being the good guys” since the jitterbug fell out of fashion.
So I’m not used to seeing something in a history textbook that isn’t from at least two of my lifetimes ago.
