I am working on a story set in a timeline where the US shifted to the right in the 60s, detente with the Soviets never happened, and we end up getting into a nuclear war in 1990. The problem is that I am having trouble figuring out how to get where I want to go. My current POD is that Kennedy backs down in the Cuban Missile Crisis and agrees to pull the Jupiter IRBMs from Turkey. Butterfly effects cause Oswald to drop his rifle when he tries to shoot Gen. Walker, and his fingerprints are matched to it when he is picked up in New Orleans for his scuffle with anti-Castro activists (that last bit happened in OTL, by the way). Kennedy never commits significant numbers of US troops to Vietnam, and Saigon eventually falls, although just when I am not sure about. Between the foreign policy failures of the Missile Crisis and Vietnam, the absence of Kennedy as a left-wing martyr, and the absence of Vietnam as a polarizing factor, the left is much weaker than in OTL, and the right dominates politics from the mid-60s to 1988.
So, my two questions are:
Is this plausible? I am not very well-versed on Cold War history.
Any suggestions for filling in the details? In particular, the course of TTL's Vietnam War-the only things I know about Vietnam I got from Bright Shining Lie. I want to keep significant US troops out of Vietnam, so that the north can conquer the country and deal a further blow to the left's reputation on foreign affairs.
