This has got to be one of the stupidest posts ever! The Cuban government has killed political prisoners and others that oppose the government, as do many violent and vicious dictatorships. The US was at war with Germany and Japan--a war that those countries started with the US. What was the US supposed to do, talk to them nicely and ask them to not be at war? Since then, let's see:
Korea: A vicious thug led Communist regime in North Korea invaded South Korea. The UN voted to intervene and the US led a coalition of forces to stomp them into the ground. The Chinese then got involved--unilaterally--and expanded the war. How is that the US's fault?
Vietnam: The US only got involved because LBJ was a lying, sack-of-shit President that used the phony Gulf of Tonkin incident to expand it. Up to that point US involvement was very limited. Nixon then got the US out of that debacle. But it did save Thailand, Malaysia, and Indochina from ending up with brutal Communist dictatorships that would have wrecked those countries.
The Dominican Civil war: Eisenhower was right to stomp the Communists in this one. The Dominican Republic is better for it too, unlike Cuba...
The Gulf War(s): Saddam brought that on himself by invading Kuwait
Afghanistan: Harboring Al Qaeda was a big mistake. The US had every right to retaliate against international terrorism.
So, there's no equivalence between Cuba killing political opposition and what the US has done post WW 2.
