Answer:
The purpose of President John F. Kennedy’s “flexible response” defense policy was to prevent a further increase in the construction of nuclear weapons.
Step-by-step explanation:
The concept of flexible response developed by President Kennedy was attached to the concept of graduated response, and sought to respond to each threat or aggression, with a response proportionated to its nature, with the hope of dominating the escalation process and leading the opponent to contain himself or negotiate. The purpose of this type of response was to avoid the onset of a large-scale nuclear war, which would only have negative consequences for all the sides in conflict.
