The peaceful end of the Cuban Missile Crisis strengthens which diplomatic principle?

Correct answer: In crisis both controlled pressure and dialogue are necessary

The direct answer is A: in a crisis, controlled pressure and dialogue are both necessary. The Cuban Missile Crisis of 1962 brought the United States and Soviet Union close to nuclear war after Soviet missiles were placed in Cuba. The United States used controlled pressure through a naval blockade or quarantine and military readiness, while leaders also used direct and secret communication to find a settlement. Step by step: nuclear weapons made uncontrolled escalation extremely dangerous; pressure showed that the missiles could not remain without response; dialogue allowed both sides to understand demands and create a face-saving compromise; the Soviet missiles were removed and the crisis ended without nuclear war. Option A is correct. Option B is wrong because war was avoided, not used as the only solution. Option C is wrong because private or back-channel communication can sometimes reduce danger. Option D is wrong because nuclear weapons create an enormous risk. Memory cue: Cuban Crisis means pressure plus communication, not reckless war.
