The two biggest nuggets I've gleaned from this so far:
1. Ho Chi Minh was simply a man who worked tirelessly to free his country and achieve independence. He took military aid from China and Russia because they offered it, not because he viewed Communism as an option. This, to me, was a singularly critical factor in our decision to send troops. The entire exercise was a revolt against colonialism, and then corrupt and incompetent government exacerbated it.
Reminds me of when we pulled into the Philippines for a port of call back in the late 80's. When we got our port briefing, they said that the night before we pulled in two marines were shot by communist rebels outside the front gate.
They were fighting against the corrupt Philippine government. After the Soviet Union collapsed they switched sides to whomever would give them support. Now they are Islamic terrorists.
The only constant is the corrupt government and people fighting against it. It has been going on since it was a Spanish colony.
