On the other hand, the Cuban missile crisis only happened because JFK had come across as weak to Khrushchev when they’d had the Vienna summit, leading Khrushchev to think he could push jfk around. The Cuban missile crisis was the result.
From wiki:
“ In retrospect the summit may be seen as a failure. The two leaders became increasingly frustrated at the lack of progress of the negotiations. Kennedy later said of Khrushchev, "He beat the hell out of me" and told New York Times reporter James 'Scotty' Reston it was the "worst thing in my life. He savaged me."[18] On the other hand, Khrushchev viewed the Summit in a much more positive light. In his memoir, Khrushchev showed ambivalence. He proclaimed, "I was generally pleased with our meeting in Vienna. Even though we came to no concrete agreement, I could tell that [Kennedy] was interested in finding a peaceful solution to world problems and avoiding conflict with the Soviet Union."[19] However, historian William Taubman suggests that Khrushchev merely felt he could "[push Kennedy around]."[20]”
