The arms race
The "Arms Race" was also known as Missile Gap. The Arms Race was a race between the USSR and the U.S to see who could make the most nuclear weapons the fastest. the U.S was the first to make an A-bomb and test it, but the USSR was right behind them. The USSR was the first to make a missile system that could shoot forms he ground and reach another continent. Then the U.S made one right after. Eventually there was the SALT and SALT II agreements made to reduce the making of the nuclear weapons, because it started to get really expensive. The Arms Race came to an end when he Soviet Union collapsed at the end of the Cold War in 1991.
