High-stakes conflict triggers fight-or-flight, reducing rational decision-making.

Shared goals reduce conflict by shifting focus from "me vs. you" to "us vs. the problem."

Using objective criteria leads to fairer, less emotional negotiations.

Privately, Kennedy agreed to remove U.S. missiles from Turkey. This allowed both sides to de-escalate while still preserving public strength.

But that’s not the end of the story.

Years later, at a 2002 conference in Havana, we learned just how close we had come to catastrophe.

During the standoff, a Soviet submarine (B-59) was operating near Cuba, cut off from communication with Moscow. Believing war may have already begun, the crew prepared to act. They had a nuclear torpedo on board and could launch if they believed conflict had started.

To force the submarine to surface, the U.S. dropped non-nuclear depth charges. Cut off and under pressure, the officers aboard B-59 faced a decision: should they launch?

The launch required unanimous agreement from three senior officers. Two voted to fire. The third, Vasily Arkhipov, refused.........
