The Eisenhower Doctrine was a policy announced by U.S. President Dwight D. Eisenhower in 1957. It aimed to provide military and economic assistance to countries in the Middle East that were threatened by communist aggression. The doctrine was a response to the growing influence of the Soviet Union in the region during the Cold War. Under this doctrine, the United States pledged to intervene if necessary to protect the sovereignty of nations facing external pressures. This policy was part of a broader strategy to contain communism and maintain stability in the Middle East, reflecting the U.S. commitment to its allies during a tense geopolitical period.
