Why did President Kennedy think the Alliance for Progress would help the United States in the Cold War?

It would give the United States powerful allies to prevent the spread of communism in Latin America.
It would enable the United States to station troops in Latin American nations that bordered on Soviet allies.
It would provide economic aid to Latin American nations where poverty was increasing the appeal of communism.
It would give the United States access to resources needed to build up its military in response to the increasing Soviet build-up.
