The Cuban revolution was a part of the broader anti-colonial struggle in the post-war period. Many of the leaders of that movement were inspired by some components of a kind of Marxist-Leninism but it was by no means the only influence.

Nor was there universal adulation of the Castro-ites by Marxists around the world.

There is a lot of criticism of the Cuban revolution, and debate whether it was in fact a revolution or a coup, within Marxism itself.

Castro himself was not a self-described socialist until after he was spurned by the U.S. who committed a major foreign policy blunder by supporting Batista, the landowner class, and the existing regime long after they had shown themselves to be brutal and corrupt and after Castro had overthrown them.

Castro threw himself into the Stalinist bloc out of necessity. Blame for the 50 year trajectory of Cuba can be placed squarely on ineptness of U.S. foreign policy to deal with the post-colonial reality. They committed similar and in fact bloodier and worse blunders in central America throughout the 70s and 80s with Nicaragua, El Salvador, Guetemala.

A very sad incompetent and shameful history that Obama looked like he was finally willing to confront.
