NATO member countries that signed a key Cold War-era security treaty froze their participation in the pact on Tuesday just hours after Russia pulled out, raising fresh questions about the future of arms control agreements in Europe.
Many of NATO’s 31 allies are parties to the Treaty of Conventional Armed Forces in Europe, which was aimed at preventing Cold War rivals from massing forces at or near their mutual borders. The CFE was signed in November 1990 as the Soviet bloc was crumbling but was not fully ratified until two years later.
