Final answer:
The Marshall Plan was aimed at European recovery post-WWII, not at preventing the spread of communism in Latin America, unlike the Alliance for Progress, Peace Corps, and military aid.
Step-by-step explanation:
The question asks which of the following was not a tactic to prevent the spread of communism in Latin America. The Alliance for Progress was indeed a program spearheaded by the Kennedy administration to encourage economic development and social reform in Latin America to deter the appeal of communism. The Peace Corps, also established by Kennedy, aimed at reducing poverty through volunteer work and showed the altruistic side of the US, contributing to the same goal. Providing military aid was a common US strategy in the Cold War to support non-communist governments. However, the Marshall Plan was focused on European reconstruction after World War II and was not specifically targeted towards Latin America to prevent the spread of communism.
