The majority of Cubans want to be free. A violent minority wants them to be communists. Using your theory, and I know you're playing the devil's advocate (as if he needs help), Cubans deserve Castro. And as for comparing the US struggle with Britain in 1176, it ignores the fact that there is an Ireland that's free of Britain. And it is at its wits end with today's IRA. The Americans who led to the US to Independence have nothing philosophically in common with the IRA.
That's 1776 not 1176.
