Can someone explain the eisenhower doctrine?

Eisenhower Doctrine, (Jan. 5, 1957), in the Cold War period after World War II, U.S. foreign-policy pronouncement by President Dwight D. Eisenhower promising military or economic aid to any Middle Eastern country needing help in resisting communist aggression. The doctrine was intended to check increased Soviet influence in the Middle East, which had resulted from the supply of arms to Egypt by communist countries as well as from strong communist support of Arab states against an Israeli, French, and British attack on Egypt in October 1956. Eisenhower proclaimed, with the approval of Congress, that he would use the armed forces to protect the independence of any Middle Eastern country seeking American help. The Eisenhower Doctrine represented no radical change in U.S. policy; the Truman Doctrine had pledged similar support to Greece and Turkey 10 years earlier. It was a continuation of the U.S. policy of containment of or resistance to any extension of the Soviet sphere of influence.
