Jack, chances are none of us can contribute anything about the music portraying the Vietnamese view of that war. And they had a much longer time to oppose that war in general - perhaps you should look to France and see how they viewed the end of their time managing that former colony. Maybe there are songs by Vietnamese in French?

The songs you heard were not the songs I heard; you had the wrong radio stations on if all you heard were easy listening crooners who masked the turmoil. It was up to you to see what else was playing. My cohort in high school was during the era when they would graduate, and if they were 18, could be drafted. I wasn't listening to Perry Como.
