I was married to a prominent Leftie (what's wrong with THAT picture ...yes, the selfsame Miss Kennebunk Dump) and was never able to get her or any of her friends (more than one of whom called me "baby-killer") to tell me why refugees were streaming southward to escape the Worker's Paradise they were all so sure NV must be.
I blame first the sex-mad, poxed, insane, doped-up invalid JFK (easily the worst president in our history ... if the crazed SOB had 15 rational minutes a day, I never saw any evidence of it) for starting it. Then, LBJ and his left-over JFK crew, particularly McNamara, for micro-managing and limiting the war from DC. To do it, they depended upon insecure Navy Communications. The Commies read our military mail for years while a masterfully organized KGB PR Campaign frightened our politicians out of their wits.
That war could have been won, as could have been Korea, if Democrats had not been in charge. It could even have been won late. Nixon and Kissinger let the commies off the hook when Hanoi should have been flattened and flooded, Haiphong closed down, and the Chicom road and rail supply line closed down. It was a replay of Ike accepting stalemate in Korea instead of wiping out Chinese sanctuary cities.
We showed the world that once you pull off the cheap trick of buying our media, we have no national guts. We are paying a terrible price for our failure to win in Korea and Vietnam because of what now turns out to have been an exaggerated fear of the Soviet reaction, which would never have happened.
