- "It shall be the policy of this nation to regard any nuclear missile crossing the embargo line that surrounds Cuba as an attack by the Soviet Union on the United States requiring a full retaliatory response upon the Soviet Union..."
- ―President John F. Kennedy's address
The Cuban Missile Crisis was a 13-day conflict that occurred between the United States of America and the Soviet Union over the deployment of American missiles in Turkey and Italy, with consequent Soviet missile deployment in Cuba. It was orchestrated by Sebastian Shaw in an attempt to cause a nuclear war that would ensure mutant dominance on Earth. However, the X-Men were able to avert the Cuban Missile Crisis, but in doing so, caused a separate mutant faction known as the Brotherhood of Mutants to form under Erik Lehnsherr's leadership.
Manipulating Colonel Hendry
Having studied genetic mutation as far back as World War II, Sebastian Shaw's goal was to bring about a nuclear war that would result in mutants becoming the dominant race on Earth. To aid him in his plans, Shaw formed a mutant group known as the Hellfire Club, whose members consisted of Emma Frost, Janos Quested, and Azazel. 
In 1962, Shaw met with Colonel Robert Hendry at Atomic to discuss the placement of Jupiter missiles in Turkey. Colonel Hendry voted against the idea, knowing full well that it could spark a nuclear war between the United States and Soviet Russia. In retaliation, Shaw had Quested and Frost use their mutant abilities against Hendry as a form of coercion. Shaw then ordered Azazel to teleport Hendry to the National Military Command Center, where the Colonel advocated for the Jupiter missiles to be positioned in Turkey. Unbeknownst to Shaw, however, Agent Moira MacTaggert of the CIA had witnessed the entire exchange with Hendry as part of her investigation into the Hellfire Club. Although she relayed the information to the CIA's director, John McCone, he did not believe her claims. This prompted MacTaggert to find an expert on genetic mutation, which led her to Professor Charles Xavier.
