A public affairs series offering compelling discussion about global politics with people from all sides of the political spectrum. "Gzero" comes at a time when the world order that has united much of the globe since the end of World War II is fraying, and global summits like G-7 and G-20 no longer have the influence they once did. Each week, Ian Bremmer, a renowned political scientist, shares his perspective on recent global events and sits down with world leaders, noted experts and newsmakers who are shaping the current international order.
