What happened during the Cuban Missile Crisis — the 13-day standoff that almost ended the world, 2017, Business Insider

A newspaper headline from during the Cuban Missile Crisis printed on October 23rd, 1962.

After Khrushchev met with his generals, they decided that it would be best that they would remove the missiles to prevent nuclear war. Khrushchev messaged J.F.K. to tell him that he would remove the missiles within 30 days. Nikita Khrushchev, leader of the U.S.S.R. (Union of Soviet Socialist Republics), fell from power just two years later because people viewed the Cuban Missile Crisis as a failure for the U.S.S.R. and they also believed he underestimated the West. During all this, they fell short on their food supply due to struggling negotiations with China.
