Final answer:
The Cuban Missile Crisis did not contribute to the conditions that led to McCarthy's rise. Instead, factors like The Red Scare, the spread of communism, and the fear of espionage created the right atmosphere for his influence to grow during the earlier Cold War period.
Step-by-step explanation:
The conditions that led to Senator Joseph McCarthy's rise were shaped by a series of events and a climate of fear during the Cold War. The contributing factors included The Red Scare, which refers to the fear of communism spreading within the United States, and the general fear of espionage after several spying incidents were uncovered. Another contributing element was the widespread concern over the perceived threat of internal security breaches by Communists within the government and other institutions.
These factors created a fertile ground for McCarthyism, which thrived on the unsubstantiated accusations of disloyalty and communism without concrete evidence. However, the Cuban Missile Crisis did not contribute to this environment as it occurred more than a decade later, in October 1962, well after McCarthy's influence had waned following his censure by the Senate in 1954. Therefore, the event that did not contribute to the conditions leading to McCarthy's rise is The Cuban Missile Crisis.
