On May 20, 1902, the United States gave Cuba its independence following a fifty year struggle, making it the last Spanish-American colony to recieve its freedom. However, the Platt Ammendment gave the United States the right to intervene in Cuban affairs to preserve Cuban independence and stability. In turn, the Platt Ammendment ensured the stability of the United States.
Cuba was an important country to the United States because of trade and military control. It was easy for ships to take goods into Cuba because of the typical Atlantic Ocean currents. Due to the Platt Ammendment, the United States and Cuba began years of interaction that involved big name players like John F. Kennedy and Fidel Castro, events like the Cuban Missile Crisis and the Bay of Pigs, and an important naval base at Guantanomo Bay.
