U.S. President Joe Biden said Thursday that he would halt the withdrawal of American troops stationed in Germany and end support for Saudi Arabia's war in Yemen as top foreign policy goals. In his first visit to the State Department as president, Biden called for a return to the "grounding wire of our global power.” He sought to cheer the diplomatic workers with his speech. Many of them had expressed unhappiness over the last several years about the policies and actions of former President Donald Trump. “America is back. Diplomacy is back,” Biden said in brief comments to State Department workers. You are the center of all that I intend to do. You are the heart of it. We’re going to rebuild our alliances.” Biden administration officials said the president was hoping to send an unmistakable signal that the U.S. is ready to return to its position as a world leader.
