After JFK started the Vietnam war, pulled the plug on the Bay of Pigs Cuba invasion, JKF was assassinated. His VP Johnson was sworn in. Johnson saw his chance for the Great Society social engineering crap, which we have been living with ever since — But the Vietnam War wouldn’t go away. So Johnson started what he called his ‘containment policy’ — But the war wouldn’t go away.
Johnson was far more interested in his Great Society crap — But the war wouldn’t go away.
So Johnson went away.
