"Blockade != Embargo."

Irrelevant distinction presently. Kindly do your research and study what is absolutely enforced via both law and unofficial pressure on third parties. Some mere cigars available in Europe and some tourists don't change the essentials.

"Cuba's problems emanate from Havana, not Washington D.C."

Only said so arrogantly by a citizen of a nation who has never suffered from economic suppression. Like slavery, you will need to experience the chains yourself, before you understand the pain and suffering. I am frankly just disgusted at citizens of the West who support such suppression through threats and force and then blame the native government. Your own nations would have experienced severe pain if forced to the same situation, but it must be great to issue declamations from your holier-than-thou throne.
