It was held May 22–30, 1972. It featured the signing of the Anti-Ballistic Missile (ABM) Treaty, the first Strategic Arms Limitation Treaty (SALT I), and the U.S.–Soviet Incidents at Sea agreement. The summit is considered one of the hallmarks of the détente at the time between the two Cold War antagonists.
