North Korean Foreign Minister Ri Yong Ho says the United States has declared war on his country. Ri made the statement to reporters in New York City on Monday. He added that his country would take counter-actions, including shooting down American warplanes. Ri directly linked the threat to one of U.S. President Donald Trump’s late-night Twitter messages over the weekend. In a tweet late Saturday, Trump wrote, “Just heard Foreign Minister of North Korea speak at U.N. If he echoes thoughts of Little Rocket Man, they won't be around much longer!” Ri had made a speech to the U.N. General Assembly earlier on Saturday. In a show of force, the U.S. sent several B1 bombers and fighter planes on a mission Saturday along the North and South Korean borders. A Pentagon spokesman said, "This mission is a demonstration of U.S. resolve and a clear message that the President has many military options to defeat any threat.”
