The Cold War was years in the making, with both sides harboring hatred. The Soviet Union felt that the United States had surrendered them in WWII, and the US dreaded socialism. Little jiibes backpedaled in forward for quite a long time, with the disdain becoming on both sides. At long last they halted on both sides when the Soviet Union began to convey weapons to Cuba and position them confronting the US (this is amid Kennedy's administration), the US advised Cuba and the Soviet Union to uproot the weapons yet they didn't. At last the US set up a barricade around Cuba keeping Soviet ships from entering at any expense. At long last Nikita Krushchev canceled his boats and the US and Soviet Union went to an understanding - if the US would uproot the atomic weapons they had in Turkey, the Soviet Union would evacuate the weapons they had in Cuba.
So fundamentally the Cold War endured so long in light of the fact that both sides simply kept on letting the disdain assemble as opposed to attempting to take care of the issues that finally ended up causing the Cold War. In any case, taking after the Cold War Kruschev and Kennedy perceived that they were so near to an atomic victory and chose to make a "hotline" between both sides - the US hotline is situated in the Pentagon and the Soviet hotline is situated in the Kremlin; both are still used right up 'til today for prompt contact between the Soviet and US rulers.
