Please elaborate on what specifically connects these two primary sources. Use the sources to provide context for your argument. https://www.marxists.org/archive/guevara/1961/04/09.htm https://www.marxists.org/history/cuba/archive/castro/1960/09/29.htm

What specifically connects the two primary sources specified in the student’s question is the identity of the two figures whose statements are posted. Let us start with the second of the two sources. Fidel Castro was the principal leader of the revolutionary movement that succeeded in overthrowing the dictatorship of Fulgencio Batista. Batista favored the United States, and his invitation to major figures from American organized crime to establish hotels and casinos on the island nation 90 miles from the United States' coast made him a sworn enemy of the rebels who removed him from power. Castro would go on to rule Cuba until his health deteriorated during the early part of the twenty-first century, at which point he was replaced by his brother and fellow revolutionary Raul. He died in 2016. The speech that was provided by the student was, as its date (September 29, 1960) indicates, given in the early phase of the postrevolutionary era. Castro’s speech is a primary source because it is the late dictator’s own words.
The other document provided is an article by Che Guevara, a medically-trained Argentine revolutionary who fought with the Castro brothers in the mountains of Cuba and who became an important figure in the Cuban government before leaving to help foment revolutionary movements across the Americas. The article, as with Castro’s speech, is an indictment of the United States and the country’s role in supporting repressive regimes in the Western Hemisphere and around the world. Both Guevara’s article and Castro’s speech are defiant in tone and hostile to the United States. What links these primary source documents is that they are both texts from the two key figures in the Cuban revolution. Both are indictments of the superpower that dominated the hemisphere.
