Cuba

Cuba began going downhill when Fidel Castro came into power as the President of Cuba.  Fidel Castro was a strong believer in Communism.  Being a complete dictator, Fidel Castro was hostile towards his men.  He then got oil from Russia.  In response to the United States refusal to refine the oil, all United States companies in Cuba such as Shell, were destroyed.  The going back and forth of non-combat "attacks" continued between the United States and Cuba.  President Eisenhower then cut the Sugar cane imports by 95%, destroying Cuban farmers.  To take matters further, he hired Cuban exiles to destroy the remaining fields in Cuba.  The competition between the US and Russia regarding nuclear missiles also grew.  Cuba was armed with Russian Missiles.  The key to winning a nuclear war was to have the First Strike.  With the new Russian missiles stationed in Cuba, the US was at a disadvantage as the travel time for the Russian missiles was now much less than the US's.  The options to rid the missiles in Cuba included Air strike, Invasion of Cuba, Diplomacy negotiations, or a quarantine, all with their own pros and cons.
