North Korea's deputy UN ambassador is warning the U.S. of nuclear war.  Kim In Ryong accused the U.S. of turning the Korean peninsula into the "world's biggest hotspot."  In a news briefing yesterday at the UN, the North Korean diplomat cited joint U.S.-South Korean military exercises and accused the U.S. of dangerously ratcheting-up tensions on the peninsula.  

North Korea attempted another missile launch over the weekend but it failed.  Responding to a question from a reporter at the White House, President Trump said North Korea must start behaving.
