Not much at all IMO. A profile of Jane Fonda can be found here: http://www.nndb.com/people/637/000022571/
Here are a couple of excerpts from her profile: She became an anti-war activist, then worked for almost any leftist cause, including desegregation, women's rights, and environmental issues, until eventually she was known as much for her political stands as for her films. She visited Alcatraz during its siege by Native Americans in 1969, and thought Rev. Jim Jones was doing good work. She supported Huey Newton's campaign for Congress, and said the Black Panthers were "our revolutionary vanguard. We must support them with love, money, propaganda and risk". During the Vietnam war, Fonda toured America with her Klute co-star and real-life lover Donald Sutherland, staging a "guerilla theater" piece called FTA (for "Fxxx the Army" or, when speaking with mainstream reporters, "Free the Army"). "If you understood what communism was", she said, "you would hope, you would pray on your knees that we would someday become communist".
Fonda has never apologized for her opposition to the Vietnam war, and she says she never will. She still asks why the US killed millions of Vietnamese people, and what more than 50,000 American soldiers died for. She has, however, apologized for those famous photos. "I will go to my grave", Fonda has said, "regretting the photograph of me in an anti-aircraft gun, which looks like I was trying to shoot at American planes. It hurt so many soldiers. It galvanized such hostility. It was the most horrible thing I could possibly have done. It was just thoughtless".
It's obvious from the first paragraph Jane Fonda lacks good sense or judgment! The woman has no respect for decency or truth IMO. Could she be the epitome of "a leopard never changes its' spots"?
