The Cuban Missile Crisis was a conflict in October 1962 between the United States on one side and the Soviet Union along with Cuba on another side. The crisis is generally regarded as when the Cold War came near to transforming into a nuclear conflict and is also the first recorded circumstances of mutual guaranteed destruction being discussed as an establishing factor in a significant global weapons agreement.
After the US had put nuclear missiles in Turkey and Italy, aimed at Moscow, and the fallen short US effort to overthrow the Cuban regime, in May 1962, Nikita Khrushchev suggested placing Soviet nuclear missiles in Cuba to dissuade any prospective intrusion effort. Throughout a conference between Khrushchev and Fidel Castro that July, a secret arrangement was finalized for building numerous rocket sites in the late summer season.
These preparations were discovered by the Defense Intelligence Agency, which on October 14, entrusted an Air Force-operated U-2 airplane with scanning the suspected locations in Cuba, securing clear photo evidence of medium-range as well as intermediate-range ballistic nuclear missiles on the ground. The United States took into consideration attacking Cuba via air and sea; however, it picked a military blockade instead, calling it a “quarantine” for lawful and other factors. The US revealed that it would certainly not allow offending weapons to be delivered to Cuba while demanding to dismantle and returning Soviet weapons to the USSR.
