Dwight David "Ike" Eisenhower (/ˈaɪzənˌhaʊ.ər/ EYE-zən-HOW-ər; October 14, 1890 – March 28, 1969) was an American politician and general who served as the 34th President of the United States from 1953 until 1961. He was a five-star general in the United States Army during World War II and served as Supreme Commander of the Allied Forces in Europe. He was responsible for planning and supervising the invasion of North Africa in Operation Torch in 1942–43 and the successful invasion of France and Germany in 1944–45 from the Western Front. In 1951, he became the first Supreme Commander of NATO. 

Eisenhower's main goals in office were to keep pressure on the Soviet Union and reduce federal deficits. In the first year of his presidency, he threatened the use of nuclear weapons in an effort to conclude the Korean War; his New Look policy of nuclear deterrence prioritized inexpensive nuclear weapons while reducing funding for conventional military forces. He ordered coups in Iran and Guatemala. Eisenhower refused to give major aid to help France in Vietnam. He gave strong financial support to the new nation of South Vietnam. Congress agreed to his request in 1955 for the Formosa Resolution, which obliged the U.S. to militarily support the pro-Western Republic of China in Taiwan and continue the isolation of the People's Republic of China.
