A promise by the United States not to invade Cuba again.

Explanation:

One of the reasons behind this condition that ended the Cuban Missile Crisis was the Bay of Pigs Invasion. Roughly one year earlier, the US supported 1,000 Cuban exiles who invaded Cuba in hopes of starting a revolution that would get rid of the communist leader Fidel Castro.
