I didn't know until recently that Kennedy also betrayed the anti-Communists in another revolution--Vietnam--by ordering the US agents to assassinate Ngo Diem, the very popular, duly elected President of South Vietnam, who had been President of all of Vietnam before the Communist invasion.
After the invasion of the Communists from the North, Diem was the country's only proven leader, and was the brains behind the only military tactic that was working against the Communists: training and arming the individual towns (where the highly motivated locals knew the terrain) to defeat the invaders.
Makes you wonder which side Kennedy and his government were on.
Good thing they had presidential immunity back then
More realistic and world-savvy men were astounded that Kennedy genuinely did not anticipate that the deaths of the Diem brothers were a near inevitable result of a coup. What did he think would happen?
Eventually, the US military under Creighton Abrams adopted an "enclave strategy" in which the South Vietnamese were trained and equipped to defend their rural countryside. This killed off the VC and the communist insurgency. Sadly, the Left in the Democratic Party then deliberately torpedoed that success by cutting off aid and letting the North Vietnamese mount a direct conventional invasion of the South for the win.
