“The President of South Korea, Moon Jae-in, has asked the U.S. to open negotiations that would allow South Korea to build more powerful ballistic missiles in order to counter an increasingly aggressive North Korea. On Friday, the government in Pyongyang fired an intercontinental ballistic missile (ICBM), its second this month, that flew about 45 minutes straight up and crashed into the sea off Japan some 620 miles away. U.S. national security advisor H.R. McMaster confirmed early Saturday that Washington had accepted Moon’s offer, and would begin negotiations shortly.”
