How did the crisis affect the relationship between the USA and USSR?
The relationship had deteriorated almost to the brink of nuclear war, so Kennedy wanted to focus more on the two nations' 'common interests'.
A hotline was set up in June 1963 between the USA and the USSR. This would help avoid crises by enabling direct and quick communication.
Because it almost led to nuclear war, both countries worked to improve their relationship and slow down the arms race.
