President Dwight D Eisenhower, elected in a landslide as the first Republican president since 1932, had a lasting impact on American life and politics. He ended the Korean War, and avoided any other major conflict. He cut military spending by reliance on very high technology, such as nuclear weapons carried by long-range bombers and intercontinental missiles. He gave strong support to the NATO alliance and built other alliances along similar lines, but they never were especially effective. After Stalin died in 1953, Eisenhower worked to obtain friendlier relationships with the Soviet Union. At home, he ended McCarthyism, expanded the Social Security program and presided over a decade of bipartisan comity. He promoted civil rights cautiously, and sent in the Army when trouble threatened over racial integration in Little Rock Arkansas. The unexpected leapfrogging of American technology by the Soviets in 1957 with Sputnik, the first Earth satellite, began the Space Race, won in 1969 by the Americans as Apollo 11 landed astronauts on the Moon. The angst about the weaknesses of American education led to large-scale federal support for science education and research. In the decades after World War II, the United States became a global influence in economic, political, military, cultural, and technological affairs.
