Nixon took part in a historic reconfiguration of Cold War policy when he agreed to the Strategic Arms Limitation Treaty with the Soviet Union. This treaty greatly decreased the possibility of nuclear warfare between the US and Soviet Union and helped relieve political tensions between these two countries. The Strategic Arms Limitation Treaty was a result of the Moscow Summit that took place in May of 1972.
