===Isolationism===

The Republican party had an isolationist wing led by Senator [[Robert A. Taft]]. During World War II, the internationalist wing of the GOP gained strength, as former isolationist Arthur Vandenberg switched sides. The leaders of the anti-isolationist or "internationalist" wing were [[Dwight D. Eisenhower]] (president 1952–60), and [[Richard Nixon]] (president 1968–74).  Conservative leader [[Barry Goldwater]] in 1964 rejected isolationism and called for an aggressive [[Rollback]] strategy to defeat Communism, a policy followed by [[Ronald Reagan]] (president 1980–88).

Meanwhile, isolationist sentiment grew in the Democratic party, largely in reaction to the failure of the [[Vietnam War]]. the chief spokesman was Senator [[George McGovern]], whose 1972 presidential campaign had the isolationist slogan, "Come Home America".
