From a report at the first link below:
But Kerry already did that when he and Jane Fonda sided with the Viet Cong in their protests toward the end of the Vietnam war.
The Communist Vietnamese honored Vietnam war protestor John Kerry. He was as a hero to them in their victory over the United States in the Vietnam War (second link below).
Why would the Russians have any respect for a turncoat like John Kerry? They liked what he did when he turned on America but understood his character for what it was.
