Islands have taken on a greater prominence when we talk about the risk of war, especially in Asia. In the Indo-Pacific, islands, reefs, and rocky outcroppings are increasingly an organizing principle for considering security issues. In this episode, Doyle Hodges hosts a conversation on the sidelines of the Bridging the Straits II conference held in Tokyo. Professor Michishita Narushige of the Japanese National Graduate Institute for Policy Studies (GRIPS), Professor Terry Roehrig of the US Naval War College, Darshana Baruah, a pre-doctoral researcher at the Sasakawa Peace Foundation, and Dr. Euan Graham, Executive Director of La Trobe Asia, discuss how the unique nature of islands influences Asia-Pacific security, ranging from the security concerns of small island nations in the Indian Ocean to China's construction and militarization of artificial features in the South China Sea, to territorial disputes between Japan, South Korea, Russia, and China over the possession of small--often uninhabitable or marginally economically viable--islands.
