It appears that he (Kerry) committed treason if the facts bear out. Especially during war time.
I spent a few years in the mid 60's close to San Francisco and I know first hand how the Fonda/Kerry leftists caused us (Army) to be humiliated/spit on/cussed out whenever we had to go off base. As General Giap says - Kerry may not have won the war for him but he kept them from losing (paraphrased). Giap admitted the north was finished after the losses of the Tet offensive and they were trying to arrange for an honorable truce BUT AFTER SEEING THE SUCCESS OF FONDA/KERRY IN TURNING AMERICA AGAINST THE TROOPS, IT TURNED IT AROUND FOR NORTH VIETNAM.
