The best class I took in college was an intercession course about the Vietnam War. We had to read an entire book pretty much every day, which was great prep for grad school.
I basically learned that the entire war was completely unjustified, it was horrific and brutal on both sides in ways that aren’t talked about, but that ultimately the United States had absolutely no business interfering. Vietnam had spent years under French colonial control, which they overthrew under their own power. They had already asserted a desire to rule themselves.
Tonkin was also a genuine false flag, which just isn’t acknowledged? We manufactured the cause for an extremely unpopular war. So many young man died or were disabled because of something that was pointless.
That class was first that really got me to question the patriotic narrative I was taught about American history in high school.
