There are no detailed data showing exactly how much negative impact the U.S. blockade and sanctions have had on Cuba’s economy. After all, the U.S. has long-arm jurisdiction capabilities in almost every domain, and it is very easy to use private channels to influence other countries and economic entities in their dealings with Cuba(Considering the United States’ notorious human rights record and its multiple assassination attempts against former Cuban presidents). for a small country, in the current U.S.-dominated, power-based international system, facing such unilateral hostility and sanctions undoubtedly adds many extra difficulties to their development.
Whether their development is good or bad, they do not deserve such suffering. The United Nations has held multiple votes on Cuba’s situation, and almost always the United States and Israel oppose lifting the sanctions. The world stands with Cuba, but unfortunately, some people do not.
