In what ways did the cold war intensify during Eisenhower's administration?

During Eisenhower's administration, the Cold War intensified through the escalation of nuclear arms competition, exemplified by the U.S. adopting a policy of "massive retaliation" and increasing its nuclear arsenal. The establishment of the Eisenhower Doctrine aimed to counter communist influence in the Middle East, reflecting a commitment to contain communism globally. Additionally, the U.S. engaged in covert operations, such as those in Iran and Guatemala, to undermine communist governments, further heightening tensions with the Soviet Union and its allies. The launch of Sputnik in 1957 also sparked fears of Soviet technological superiority, prompting a U.S. response that included increased funding for science and education.
