While Fonda did indeed "show aid and comfort to the enemy," many of the
stories related in the post (and ongoing e-mail) are just plain made up.

From http://www.snopes.com/military/fonda.htm:

The most serious accusations in the piece quoted above -- that Fonda
turned over slips of paper furtively given her by American POWS to the
North Vietnamese and that several POWs were beaten to death as a result
-- are proveably untrue. Those named in the inflammatory e-mail
categorically deny the events they supposedly were part of.

"It's a figment of somebody's imagination," says Ret. Col. Larry
Carrigan, one of the servicemen mentioned in the 'slips of paper'
incident. Carrigan was shot down over North Vietnam in 1967 and did
spend time in a POW camp. He has no idea why the story was attributed to
him. "I never met Jane Fonda."

The tale about a defiant serviceman who spit at Jane Fonda and is
severely beaten as a result is often attributed to Air Force pilot Jerry
Driscoll. He has repeatedly stated on the record that it did not
originate with him.

The story about a POW forced to kneel on rocky ground while holding a
piece of steel rebar in his outstretched arms is true, though. That
account comes from Michael Benge, a civilian advisor captured by the
Viet Cong in 1968 and held as a POW for 5 years. His original statement,
titled "Shame on Jane," was published in April by the Advocacy and
Intelligence Network for POWs and MIAs.

The unknown author of the "Hanoi Jane" e-mail appears to have picked up
Benge's story on-line and combined it with fabricated tales to create
the forwarded text. Some versions now circulate with Benge's name
listed; others quote his statement anonymously.
