The Cold War didn’t take place anywhere. It’s refering to the relationship of Russia and The U.S. at the time after World War 2. It was close to war after The Cuban Missile Crises. Russia had placed nukes in Cuba. With them being so close, they could have hit most cities in the U.S. Fortunatley, both sides realized it would be total annihaltion for all if one fired a nuke at the other. It would have continued until we were all dead.
