I remember her being outspokenly anti-war spoke against all U.S. troops over there and did a photo-op with North Korean troops. In later years she said that she regretted what she did, even though she still felt it was wrong for us to get into the war.
I have mixed feelings about the conflict. Our government lied to get us into the war and as it dragged on, it cost over 58,000 lives. That said, the South Vietnamese government was democratically elected, and the U.S. was on a mission to stop what they perceived as a Communist Domino Effect, so they joined a multi-nation force against the Communists.
What a lot of people don't realize is that by the time we left, the Viet Cong guerillas had been completely destroyed and we were beating back the NVA, but massive public pressure forced us out, rather than us outright losing. The mistake was allowing unfettered media video access to combat units which showed the dead and dying U.S. troops in the public's living rooms. They learned their lesson for future conflicts though. They limited news media access to combat situations.
