What was the purpose of President JFK flexible response defense policy?

President John F. Kennedy's flexible response defense policy aimed to provide the United States with a range of military options to address various levels of conflict, rather than relying solely on nuclear deterrence. This strategy sought to enhance the U.S. ability to respond to conventional threats, insurgencies, and nuclear crises with appropriate military force. It emphasized the importance of being able to engage in limited warfare and counterinsurgency efforts, thereby promoting a more adaptable and nuanced approach to Cold War challenges. Ultimately, flexible response was intended to deter aggression while minimizing the risk of escalating conflicts into nuclear confrontations.
