Where this departs from our timestream: The 1960 US Presidential Election: Nixon wins!
Things went badly for Richard Nixon and his country after that. Cuba became a serious hot spot in the cold war, and in 1962, it boiled over. There was a brief but terrifying nuclear exchange between the USA and the USSR, that fortunately was low in casualties, but pushed many voters towards the more pacifistic parties that emerged. By 1964, the US Peace Party was able to win all major federal and state elections, and there arose a new superpower: Hippie Nation.
President Abbie Hoffman charged his country with a new course, one of Peace, and "volunteers" flooded to join the new Peace Army. They travelled the world, bringing peace and love to strife torn areas. Often they flew in the newly designed Volkswagen-Bell Type 2 Helicopter, knows as the "Hippie Huey", or the "HippyHoppy".
