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.
