SEOUL, Feb. 5 (UPI) -- North Korea denounced the United States and South Korea for "dangerously playing with fire," citing the upcoming Key Resolve joint military exercises and a bilateral strategy to detect, defend, disrupt and destroy missiles, also known as 4D.
Pyongyang's state-controlled media said Friday, "The infamous and novel method of nuclear strike is to be introduced during the Key Resolve joint military exercises, and in accordance with 4D operational plans, and if so there is no doubt it would heighten the risk of nuclear war on the Korean peninsula in an act that is dangerously playing with fire," Yonhap reported.
