The "Reagan Doctrine" was used to characterize the Reagan administration's (1981-1988) policy of supporting anti-Communist insurgents wherever they might be. In his 1985 State of the Union address, President Ronald Reagan called upon Congress and the American people to stand up to the Soviet Union, what he had previously called the "Evil Empire": "We must stand by all our democratic allies. And we must not break faith with those who are risking their lives--on every continent, from Afghanistan to Nicaragua--to defy Soviet-supported aggression and secure rights which have been ours from birth."

Breaking with the doctrine of "Containment" established during the Truman administration, President Ronald Reagan's foreign policy was based on John Foster Dulles' "Roll-Back" strategy from the 1950s in which the United States would actively push back the influence of the Soviet Union. Reagan's policy differed, however, in the sense that he relied primarily on the overt support of those fighting Soviet dominance. This strategy was perhaps best encapsulated in NSC National Security Decision Directive 75. This 1983 directive stated that a central priority of the U.S. in its policy toward the Soviet Union would be "to contain and over time reverse Soviet expansionism," particularly in the developing world. As the directive noted: "The U.S. must rebuild the credibility of its commitment to resist Soviet encroachment on U.S. interests and those of its Allies and friends, and to support effectively those Third World states that are willing to resist Soviet pressures or oppose Soviet initiatives hostile to the United States, or are special targets of Soviet policy."
To that end, the Reagan administration focused much of its energy on supporting proxy armies to curtail Soviet influence. Among the more prominent examples of the Reagan Doctrine's application, in Nicaragua, the United States sponsored the contra movement in an effort to force the leftist Sandinista government from power. And in Afghanistan, the United States provided material support to Afghan rebels--known as the mujahadeen--helping them end Soviet occupation of their country.
