Oceans are at the center of global competition, climate, and trade. In his new book, “To Rule the Waves: How Control of the World’s Oceans Shapes the fate of the Superpowers,” published by Scribner, Brookings Senior Fellow Bruce Jones takes readers on a fascinating voyage through this water world via the great ports, ships, geographies, and history of our ocean planet. And on this episode of the Brookings Cafeteria, Jones shares some highlights from the book, including his visits to one of the largest cargo ships in the world and a naval base in Norway over a hundred miles north of the Arctic Circle. Also on this episode, Senior Fellow David Wessel explains one unnoticed provision of the 2017 Trump tax bill, the Opportunity Zone, which was intended to encourage development in poor neighborhoods around the country but instead unleashed a tax break gold rush for economic and political elites.
