President Ronald Reagan - Farewell Address January 11th, 1989 Ronald Wilson Reagan (/ˈreɪɡən/ RAY-gən; February 6, 1911 – June 5, 2004) was an American politician and actor who served as the 40th president of the United States from 1981 to 1989. A member of the Republican Party, his presidency constituted the Reagan era, and he is considered one of the most prominent conservative figures in American history In 2008, British historian M. J. Heale summarized that scholars had reached a broad consensus in which "Reagan rehabilitated conservatism, turned the country to the right, practiced a 'pragmatic conservatism' that balanced ideology with the constraints of government, revived faith in the presidency and American self-respect, and contributed to critically ending the Cold War", which ended with the dissolution of the Soviet Union in 1991. Many conservative and liberal scholars have agreed that Reagan has been the most influential president since Roosevelt, leaving his imprint on American politics, diplomacy, culture, and economics through his effective communication of his conservative agenda and pragmatic compromising. During the initial years of Reagan's post-presidency, historical rankings placed his presidency in the twenties. Throughout the 2000s and 2010s, his presidency was often placed in the top ten. Many proponents, including his Cold War contemporaries, believe that his defense policies, economic policies, military policies, and hard-line rhetoric against the Soviet Union and communism, together with his summits with Gorbachev, played a significant part in ending the Cold War. Professor Jeffrey Knopf argues that while Reagan's practice of referring to the Soviet Union as "evil" probably made no difference to the Soviet leaders, it possibly gave encouragement to Eastern European citizens who opposed their communist regimes. President Truman's policy of containment is also regarded as a force behind the fall of the Soviet Union, and the Soviet invasion of Afghanistan undermined the Soviet system itself. Nevertheless, Melvyn P. Leffler called Reagan "Gorbachev's minor, yet indispensable partner, setting the framework for the dramatic changes that neither anticipated happening anytime soon”
