A statement of US foreign policy issued by President Eisenhower after the Suez War and approved by Congress in 1957. It proposed to offer economic aid and military advice to governments in the Middle East who felt their independence threatened and led to the USA sending 10,000 troops to Lebanon (1958) when its government, fearing a Muslim revolution, asked for assistance. Britain had also sent troops (1957) to protect Jordan, and despite Soviet protests US and British forces remained in the Middle East for some months. The Doctrine, whose assumption that Arab nationalism was Soviet-inspired came to be seen as fallacious, lapsed with the death (1959) of the US Secretary of State, John Dulles.
