Because a lot of people felt that way, the government could not prosecute her for treason. What Fonda did and said WAS treason, of course (I worked it out at the time, with difficulty and realized if that wasn't treason, nothing was) but they were losing the college-educated young people, and Jane Fonda was the popular, beautiful daughter of Hollywood legend Henry Fonda. So it wasn't going to happen.Fifty thousand young guys (many enslaved via the draft) died needlessly in that fucking useless fiasco. It made me ashamed to be an American.
I escaped it by joining the Navy.
And Jane Fonda remains a hero of mine for doing what she did.
So now they can't try anyone for treason, even flamboyant cases like that Bradley Manning character who gave all the U.S. military data to Wikileaks.
