The Cold War was a war over ideology between B) the United States and the Soviet Union. The United States was essentially a capitalist society, while the Soviet Union lived under communist rule. The Cold War was not an armed conflict, but was political and military tension which existed between the two large countries after World War II, but also existed between the Western Bloc (US's allies) and the Eastern Bloc(Soviet Union's allies).
Well the main difference was that the South was using slaves while the north were already using machines and the north never used slaves
This is a bit complicated:
Cuba was under Fulgencio Batista's reign by the time of Castro's rise. Cuba was a capitalist country at that point that was basically the US' puppet. Fidel Castro and his "guerrillas" were obviously against the system that was being employed for many reasons. I believe one of the main reasons was that Batista's Cuba was a corrupt one. There were many under-the-books assassinations just because they were a threat to Batista, etc. Overall, Cuba was a very corrupt and injust country at that point and that is why Fidel decided to fight against it, beginning with the "27 de julio movement" alongside Ernesto "Ché" Guevara.
