She wore their uniform. In WW2 she’d been tried as a traitor. Should have had her passport revoked for what she did. Then she could have lived in the workers paradise she advocated for.
I read a book years ago that claimed there was some discussion about having her tried for treason at the time. According to what I read the thing that made everyone back off was respect for her father.
Regardless of what she says,the impression she gave by this vile act of being anti-American is the correct one. Her far Left activism before and since her Hanoi visit confirms the fact the she is an enemy of America. She is a traitor and should have been punished for that long ago.
