Explanation:

The US was against communism during the Cold War. After the Cuban Revolution, it was worried Cuba would become a Communist country. The Bay of Pigs invasion was in 1961, not immediately after the revolution (which ended in 1959). The US didn't support Castro. And it didn't send troops to take control of the Cuban economy in the way described.

Answer:

The United States was concerned Cuba was becoming a Communist country.
