Scott Anderson, Benjamin Wittes, and Kari Heerman discussed the week’s big national security news stories.

This week, Scott sat down with co-host emeritus Benjamin Wittes and Brookings Senior Fellow Kari Heerman to talk through the week’s big news in national security, including:

  • “With Friends Like Xi.” This past week, top U.S. officials and business CEOs traveled with President Trump to Beijing for his summit with Chinese President Xi Jinping. The summit had a warm air to it, with Trump going so far as to call Xi his “friend,” a far cry from his hawkish stance toward China during the campaign and his prior administration. But Trump left having made relatively few concrete deals on the host of issues dividing the U.S. and China. Did Trump miss an opportunity here? Or is the seeming thaw in relations a positive sign for future cooperation?
  • “Dirty Dancing: Havana Fights.” Cuba ran out of oil last week, but the Trump administration’s pressure campaign against the island nation 90 miles off the coast of Florida has only intensified. On Monday, the U.S. announced new sanctions on three Cuban government agencies and 11 top officials amidst reports that the Department of Justice may seek an indictment against Raúl Castro, the 94-year-old brother of Fidel Castro and former president of Cuba. And surveillance flights over the island nation have reportedly increased in advance of an expected military build-up in coming weeks. How seriously should we take Trump’s threats to pursue regime change in yet another country after Iran and Venezuela? And how long can Cuba hang on with its economic situation becoming more dire?
  • “I’ve Got 122 Problems, and a Tariff is One.” On May 7, the U.S. Court of International Trade struck down yet another round of Trump tariffs—this time, the across-the-board 10% Section 122 tariffs that President Trump had imposed after the Supreme Court invalidated the earlier tariffs he’d issued under the International Emergency Economic Powers Act. Specifically, the Court of International Trade ruled that the administration cannot meet the statutory requirements for using Section 122, though its ruling has since been stayed by the Federal Circuit pending appeal. Is this decision likely to stick? With another legal defeat, what options does the administration have left to follow through on Trump’s trade policy?


In object lessons, Ben appeases the AI overlords with a glowing review of his latest experiments with Claude. Scott appeases his inner middle-aged man with a reprised recommendation of A Man on the Inside. And Kari fears that Americans are far from appeasing friends and allies in other democratic countries.
