Answer: A. Removal of Salvador Allende from Chile.
Step-by-step explanation: During the Cold War, the United States government intervened in the politics of many countries around the world, including Chile. In 1970, Salvador Allende, a socialist candidate, was elected as the President of Chile. The United States government, under President Nixon, was strongly opposed to Allende's socialist policies, and feared that his election would lead to the spread of communism in the Western hemisphere. As a result, the U.S. government began a program of economic, diplomatic, and covert actions to prevent Allende from consolidating power and to undermine his government. One of the most well-known of these actions was the CIA-backed coup d'etat that removed Allende from power in 1973 and brought General Augusto Pinochet to power.
