arms control agreement

an agreement between two or more countries to limit or reduce the number or capabilities of weapons and related systems. These agreements can address a wide range of factors, from how many of a given weapon (such as nuclear warheads) each side has, to how powerful the weapons are, to where and under what conditions they are deployed. Monitoring to verify each side’s compliance is often included. Arms control agreements are a tool to promote cooperation and limit arms races, as occurred between the United States and the Soviet Union during the Cold War.
