I was talking specifically about the Vietnam war and the peaceful protests which helped to end it earlier than it would have. You were there? Please elaborate.
The "Vietnam War" was NOT a "War" unto itself. It was a part of a much wider war, known at the "Cold War" as was Korea, actions in Yugoslavia, Poland etc etc etc. It sort of started, according to revisionist history, in post WWII Germany. The "action" that is widely recognized to have started it was the " Berlin Blockade" (although in reality it started in the early to mid 1800's)
The "Cold War" was fought in a wider area of the globe that either WWI or WWII were fought in and overlapped both.
Not all Vietnam protesters were "peaceful", although many were. There were many radical, violent, "protesters", who killed, robbed, etc, to further their cause. William Ayers is a prime example of one who resorted to violence.
As to what your father did, I have no idea and will take your word for it. I did not know your father.
Keep in mind that the "Modern" communist movement, for lack of a better term, started in the Netherlands in the 1800's. They were VERY active in what is now known as "Vietnam", it was known as "French-IndoChina" when my father was there. That is where he received the "message" to cease hostilities when WWII ended. I have NO idea what your father was doing at that time or where he was.
History spans FAR greater time spans that is taught in "modern" schools and seldom teaches the ENTIRE story.
