What method was used by the United states to prevent communism in Latin America?

The United States primarily used a combination of economic aid, military intervention, and covert operations to prevent the spread of communism in Latin America during the Cold War. This included initiatives like the Alliance for Progress, which aimed to promote economic development and counter revolutionary movements, as well as direct military support for anti-communist regimes. Additionally, the U.S. employed covert actions, such as the CIA-backed coups, to destabilize leftist governments perceived as threats, exemplified by the overthrow of Chile's Salvador Allende in 1973.
