Final answer:
The Eisenhower Doctrine allowed Middle Eastern countries threatened by communism to seek military assistance from the United States as a part of a foreign policy move to counter Soviet influence in the region.
Step-by-step explanation:
The Eisenhower Doctrine allowed Middle Eastern countries threatened by communism to seek military assistance from the United States. This was a foreign policy statement by President Eisenhower in response to the Suez Crisis, where he pledged to send economic and military aid to any nation resisting attack by “any nation controlled by international Communism.” The doctrine aimed to assure Middle Eastern leaders that the United States would stand by them as long as they were opposing Communism. The establishment of this doctrine was a direct response to the growing influence of the Soviet Union in the region, and the need for the United States to protect its strategic interests, especially concerning access to oil.
