The military command of North Korea says that if South Korea and the United States don’t cancel their joint military exercises  by March 11, they can consider that whole 60-year-old armistice agreement totally over. The newest threat comes as China and the U.S. are reportedly drawing up new sanctions that they have negotiated together  and will submit the U.N. Security Council to punish the DPRK for its nuclear weapons test last month.
South Korea and the United States began a series of “war games” on March 1 , an annual exercise that serves as reminder to the North about the united front they face from the two allies. It’s also a helpful reminder that that Korea War has never technically ended . The DMZ that divides the peninsula enforces an armistice agreement that was signed in 1953. It was designed to create a cease-fire “until a final peaceful settlement is achieved ,” but that never happened and no formal peace treaty was ever agreed to. That’s why the U.S. Eighth Army  never left and two nations are in a near constant state of belligerence.
