“The US and Soviet Union were fighting a Cold War during this time. The US was supporting democracy, while the Soviet Union was supporting Communism. Cuba and the Soviet Union quickly became allies and began trading food, weapons, and supplies with each other.” Why did Cuba and the Soviet Union become allies?

How do you think this new alliance affected the relationship between Cuba and the US?

Cuba and the ussr became allies because Cuba and US had political disagreements as well as violence between the two and when the US refused to trade with them they made a alliance with the USSR

The US viewed Cuba as a security threat because they where in a alliance with the USSR

so they stopped trading.

With Cuba being so close to the United States the Soviet Union could use the nukes they placed in Cuba to hit the most important parts of the United States, The Soviet Union and Cuba both wanted to expand communism, and this relationship between Stalin and Castro, was an economic one so Stalin could send military personal to Castro and this helped Cuba stay defended if the U.S launched a high risk attack.  

The alliance affected the relationship between Cuba and the US by Cuba being watched by the Soviet Union so any time an attack was held on cuba it was most likely an illegal one or a very high risk spy mission, so the Americans were consistently in the red entering Communist Cuba and at risk of setting off nuclear war.
