The statement that best describes the role of Cuba during the Cuban Missile Crisis is:
Cuba sought protection from the Soviet Union and allowed the placement of missiles in Cuban territory after the failed Bay of Pigs invasion.
This accurately reflects Cuba's situation at the time, as Fidel Castro sought support from the Soviet Union following the Bay of Pigs invasion, which was an unsuccessful attempt by U.S.-backed Cuban exiles to overthrow the Castro regime. The placement of Soviet missiles in Cuba was a strategic move to protect the island and counter U.S. influence in the region.
