Dwight D. Eisenhower
34th President 1953-1961
One of the first things Eisenhower did once in office was threaten nuclear war with China after they began to build up troops in Kaesong. The Chinese decided to back down. Eisenhower also managed to secure an armistance between North and South Korea, which remains today. These events were a part of Eisenhower's plan to stop the spread of Communism in East Asia, a result of what he called the dominoe effect.
In 1957, the Eisenhower Doctrine was delivered by Eisenhower and stated that America would come to the economic aid of friendly Middle Eastern countries being attacked by other nations. This, of course, was another attempt to counter the Soviet Union, who had increased interest in converting the Middle East to Communism to aquire much need oil. This was a direct result of the Suez Crisis
