Russian Duma abolishes Cold War military agreement.

The lower house of Russia's parliament has voted unanimously to formally withdraw from the Treaty of Conventional Armed Forces in Europe, a key Cold War-era security deal. President Vladimir Putin introduced a draft bill last week "denouncing" the treaty, which aimed to prevent Cold War rivals from massing forces at or near mutual borders. Moscow first announced its intention to withdraw from the agreement in 2015, citing NATO's expansion into Central and Eastern Europe as a reason. Completing the withdrawal process is expected to take about six months.
