They disdained her for going to Hanoi, North Vietnam and actually meeting the enemy. The brothers, who had supported landlord-slaughterer Ho Chi Minh and his regime so strongly by doing a lot of propaganda in his favor on the American home front, felt she was so wrong to actually outright go out there and meet leaders of the enemy in support. Interesting!

Now more just about her. The brothers supported Minh in 1968 while he was still alive and running NV (that is about them). Did she actually ever support Minh himself? Or just his equally and totally ruthless successor Le Duan? When she made her infamous, traitor visit to NV in 1972 Minh was dead by three years. I have done enough research on this to say that she only majorly supported Duan. She and film co-star Donald Sutherland made a film in support of Duan in the very early 70's.
