Kennedy was young, naive, and inexperienced. We should have taken out Fidel when we had the chance. Now the lives of many Cubans have been lost to communism and dictatorship. Nixon was the better choice.
We should have worked with Fidel when we had the chance. Castro greatly admired the United States before they tried to kill him 30 times.
Only if it meant liberation for Cuba. I'll tell you what I wouldn't have minded going there instead of Iraq but Iraq, that liberated even more people. Those Cubans would be better off as the 51st state.
