Vice President Pence visited U.S. and South Korean troops near the Demilitarized Zone April 17, in part to show support for their efforts and to warn North Korea to curb aggressive tendencies or face consequences. “All options are on the table as we continue to stand shoulder-to-shoulder with the people of South Korea,” Pence said. His trip came as North Korea tried unsuccessfully to launch a test medium-range missile. He urged China to step forward and use its influence to urge North Korea leader Kim Jong Un to forego development of nuclear weapons. “We are heartened by some initial steps that China has taken in this regard, but we look for them to do more,” Pence said.
