The foreign policy of President Reagan that involved supporting anti-communist revolutions through direct and indirect means during the Cold War is known as the Reagan Doctrine.
This doctrine aimed to counter the influence of the Soviet Union by providing support, including military and financial assistance, to anti-communist resistance movements around the world. It was a significant shift from the policy of détente, which sought to ease tensions with the Soviet Union. The Reagan Doctrine was applied in various regions, notably in Latin America, Africa, and Afghanistan, where the U.S. supported groups opposing communist governments or movements.
In contrast, NAFTA refers to the North American Free Trade Agreement, Détente is related to the easing of geopolitical tensions, and Reaganomics pertains to the economic policies associated with Reagan's presidency focusing on tax cuts and deregulation.
