October 28th

On this day - 28th October 1962 - Ended the Cuban Missile Crises 

The cuban missile crises lasted from the 16th to the 28th of October and was one of the most intense issues during the cold war. It was the closest the cold war came to become a warm, and potential nuclear, conflict. The reason for the conflict was the Soviet Unions deployment of ballistic missiles on Cuba after US failed "Bay of Pigs Invasion" of Cuba. After this followed a series of minor conflicts, including the US dropping of "Depth Charges" on a nuclear armed Soviet submarine and a military blockage by the US. On the 28th was finally an agreement between Kennedy and Khrushchev reached and agreed on by both sides.
The Soviet Union agreed to dismantle their offensive weapons on Cuba in exchange for an U.S official declaration to never invade Cuba without direct provocation. The US also agreed, in secretly, to dismantle U.S built Jupiter missiles in Turkey and Italy. As a result of the conflict was a hotline between Moscow and Washington established. The conflict became an embarrassment for Khrushchev, who fell from power only two years later.
