When did the United States commit to placing ground troops in the Middle East? Did George Bush, Sr., or Jr., invent the doctrine? No.
The Eisenhower Doctrine, a message to Congress on 5 January 1957, was the foreign policy of U.S. President Dwight D. Eisenhower. The doctrine stated that the United States would use armed forces upon request in response to imminent or actual aggression to the United States. The doctrine made it clear that the U.S. would intervene in the Middle East against aggression. George Bush did not invent the doctrine; the Eisenhower Doctrine was U.S. policy for years before Bush.
The military action provisions of the Doctrine were applied in the Lebanon Crisis the following year,
in 1958, when America intervened in response to a request by that country's president.
The more things change, the more things stay the same.
