Finally we know the truth :)

Jane Fonda visited Hanoi in 1972 at the instigation of her secret lover Richard Nixon. (Roger Vadim had given her a taste for tall, dark, strange men.) Her mission was to pose as a dumb, treacherous, liberal, anti-Vietnam protestor, lull the Commies into a false sense of security with her breasts and coquettish manner, and sneak homing beacons onto NVA anti-aircraft gun emplacements—all of which were subsequently destroyed on B-52 bombing raids ordered by her secret lover. She also smuggled back messages from downed U.S. pilots, concealing them in a body cavity not likely to be searched by the North Vietnamese. Unfortunately, the letters gave her a painful infection, as did her affair with Nixon, which is the source of Hanoi Jane's lifelong resentment of American prisoners of war. This explains her infamous statement that returning POWs who claimed to have been tortured and brain washed were "hypocrites and liars." That wasn't the real, kind, generous Jane talking; it was the poxy jilted lover.

Must be true, it’s on the internet………..
