MUNICH, GERMANY - FEBRUARY 18: U.S. Vice President Mike Pence delivers a speech at the 2017 Munich Security Conference on February 18, 2017 in Munich, Germany. The 2017 Munich Security Conference, which brings together leading government figures from across the globe to discuss issues of common security concern, is taking place in the wake of the ascendence of Donald Trump to the U.S. presidency and the appointment of a new U.S. government cabinet. Trump has repeatedly called for a more isolationist United States, which has caused alarm among many world leaders concerned about the U.S.'s continued commitment to matters of global security.
