what's up with cuba?

When Fidel Castro took the power as president in the early decade, cuba began striking downhill. Castro was an extreme communist and a complete dictator, he was both hostile and completely ruthless to his men and to the cuban population as a whole. Cuba refused to collaborate and refine oil for them which led to the economic sink of many large companies such as shell. The united states and cuba were going back and forth with what they called "non combat attacks". 34th president Einshenhower decided to cut the sugar cane import from cuba to the US by more than 95% destroying many cuban farms by leaving families homeless and jobless. Cuba being a very underdeveloped country struggle a lot and agriculture was one of the main things that was able to keep its economy going. US president took it a but too far by hiring cuban spies and fire up the farmer's fields. Besides strains between those two nations there was also a lot of rivalry between russia an the US regarding Nuclear missiles. Cuba at the time was armed with russian Missiles, and the last step they had to take in order to win the war was to launch those missiles. The US was greatly disadvantaged by having their enemy's missiles right next to theirs. The russians were a lot closer to the US but the US were still far from russia. In the end the war resulted in a huge disaster and until a year ago, americans were not welcomed to cuba.
