You hadn't heard of Mi Lai? That's like know about the Iraq war but not Abu Ghraib, the war on terror but not Gitmo. If I had to list things to know about the Vietnam war, Mi Lai would be in the top five. If people are hearing about the Vietnam war, but not that part, then American media indeed has problems communicating history.
Consider that in Italian high school study plans, history "stops" at WW2, sometimes right after. I never got exposed to the Vietnam War as a history topic, and I've got my information like many others in my generation in Italy mostly from Rambo movies. Want another one? I had no idea Nixon bombed Cambodia secretly for five years until I visited Cambodia, also in 2017, and visited the landmine museum near Seam Reap.
