For this project, I questioned how Fidel Castro went about angering the United States, and what was the final breaking point in the relations between Cuba and the United States. I think this is worthwhile because a lot of people don’t actually know why the United States hated Castro so much, other than his left-wing tendencies. The beginnings of the Castro regime, the entire era, honestly, is not generally understood by the American public, which is why it should be known what was occurring between him and the United States. From what I researched, I believe that the reason Castro angered the United States so much was through cutting off their profit in Cuba by nationalizing foreign assets, and the final breaking point was the Bay of Pigs invasion of 1961, with the Cuban Missile Crisis only worsening hostilities. However, the Crisis did make the two sides reconsider how to approach the situation; the introduction of nuclear weaponry had not fared well for either of them. For my primary sources, the bulk of my search was spent on the National Archives, due to their extensive log of history regarding Fidel Castro. The historical significance of my research is that the events I discuss affected Cuba-U.S. relations all the way up until today, and propaganda has affected millions’ understandings of what happened during those times. I seek to undo what they learned.
