The U.S. government has waged a 55-year war on the Cuban people through blockade, sabotage, attempted invasions, assassinations and terrorist attacks. This government is not some third-party bystander. As an aggressor, it has no standing whatsoever to assume a position on what should happen in Cuba, certainly not to make demands. Its only legitimate policy would be to provide reparations.
The imperialists showed what they prefer as a politics in El Salvador, Colombia, Guatemala, the Condor nations and most of Latin America at times, as well as around the world.
Unlike many countries in the region Cuba, has not been the site of U.S.-backed murder regimes that killed literally tens or hundreds of thousands of civilians for deviating from the capitalist-authoritarian line. That is what the U.S. policy attempted to bring to Cuba.
The Cuban government could have never survived without substantial popular support. If the people who live there want an example of a hellish dictatorship violating all norms of human behavior, torturing and killing people, defying the entire world, they actually do have one on their island. It's in a United States military base at Guantanamo.
As an American, do you want to pontificate about how the Cuban people should live? Start by providing a different example. End the war on Cuba. Apologize. Pay reparations. Give back Guantanamo.
