Secretary of State Rex Tillerson warned Friday that military action against North Korea was "on the table" if the country continued to develop its weapons program. "If they elevate the threat of their weapons program to a level that we believe requires action then that option is on the table," he told a press conference in South Korea. The Secretary of State is on a three-country tour to the region amid heightened tensions on the Korean peninsula following recent North Korea missile launches, and fears it’s preparing for another nuclear test.
