How did the Reagan Doctrine affect the Cold War?
Similarly, how did Ronald Reagan impact the Cold War?
The foreign policy of the Ronald Reagan administration was the foreign policy of the United States from 1981 to 1989. The main goal was winning the Cold War and the rollback of Communism—which was achieved in Eastern Europe in 1989 and in the end of the Soviet Union in 1991.
Regarding this, how did the Cold War change foreign policy?
In the years after World War II, the United States was guided generally by containment — the policy of keeping communism from spreading beyond the countries already under its influence. The policy applied to a world divided by the Cold War, a struggle between the United States and the Soviet Union.
Reagan's policies stressed conservative economic values, starting with his implementation of supply-side economic policies, dubbed as "Reaganomics" by both supporters and detractors. His policies also included the largest tax cut in American history as well as increased defense spending as part of his Soviet strategy.
