At G-20, Can Donald Trump Stop Being the Wrecking Ball of the Postwar Global Order?

Donald Trump has become the wrecking ball of the postwar global order--and he clearly revels in its destruction. So far, he has little to show on big-ticket challenges, including Russia, China, North Korea, Middle East peace and Iran, international trade and tariffs, or arms deals. His next big test is this weekend, in Buenos Aires, at the G-20 summit, convening the world's largest economies and weightiest powers. All of those issues will be on his agenda in one venue. On Thanksgiving, Trump--who recently gave his Presidency an A-plus--said he is confident about his prospects at the G-20 summit, including negotiations with China's President, Xi Jinping, to avoid a trade war.
