Geez! Tell us something we don’t know.
You know....he went to Vietnam!
He , Kerry, was sent to Vietnam. After some questionable encounters he came back to the US a devoted pacifist/anti US person and volunteered for anti war demonstrations. He gave up all rights as to being a war hero when he threw his medals over the fence. Of course hooking up with a millionaire heiress who had the idea her family wealth came from communists buying catsup got him onto the political stage. Many persons in the US were sold on his kind of patriotism. He is what I call a sham US citizen.
