Is this a serious question ? Read this first: https://en.wikipedia.org/wiki/United_States_embargo_against_Cuba https://en.wikipedia.org/wiki/United_States_embargo_against_... Recently, the U.S. decided that Cuba can no longer import any oil, and they are enforcing that. Is this a surprise that the grid collapses in those circumstances ? Communism is bad (I'm from Eastern Europe...), but this collapse has nothing to do with communism. It has everything to do, with the U.S. deciding unilaterally that Cuba needs to fall.
