In what ways did president kennedy rely on the policies of brinkmanship and mutually assured destruction during the cuban missile crisis?

President Kennedy relied on the policy of brinkmanship as he allowed the situations to escalate to the verge of going into war without actually going into war in order to coerce the Soviet Union to back down. Given that both countries had the capability to completely destroy the other, this strategy was ideal by the idea of Mutually Assured Destruction as neither countries were willing to start war
