Gregg Easterbrook is the author of a dozen books, including most recently, The Blue Age: How the US Navy Created Global Prosperity – and Why We’re In Danger of Losing It. In this episode, he discusses the US Navy’s irreplaceable role as a peacekeeper on the high seas, why the age of supercarriers is likely over, the future of shipping through the Arctic Ocean, icebreakers, nuclear propulsion, the Law of the Sea Treaty, and why an armed conflict between the US and China is unlikely.
