The last high school history book I looked at (around 2000) had only half a page about World War II. Maybe a paragraph about the Vietnam War.
It is worse now, they pick an event out of history with no background and discuss “feelings” about that event. One startling example of that was a teacher taught for days about the US bombing Hiroshima and Nagasaki. Didn’t even mention Pearl Harbor and little about the rest of the war. How does it make you feel that we bombed two major cities in Japan?
We wonder why so many young people are clueless about our history and hate our country so much?
This is pretty much what they teach about WWII:
The Soviet Union defeated Hitler single-handedly
We were evil for bombing Dresden and Hiroshima/Nagasaki
Japan just wanted to kick Western Imperialists out of Asia
