Russian President Vladimir Putin and Belarus' counterpart Alexander Lukashenko met in Sochi to discuss the deployment of tactical nuclear weapons in Belarus, which is set to begin in early July. This is the first time Russia has deployed nuclear weapons outside of its borders since the fall of the Soviet Union, and is seen as a warning to the U.S.-led NATO military alliance. The deployment of nuclear weapons is a way for Russia to demonstrate its commitment to its ally and to deter any potential aggression from the West.
