Journalist and author Fareed Zakaria hosts this in-depth look at the major global developments of the week (the title's "GPS" stands for "Global Public Square"), with an emphasis on new ideas and innovative solutions to the World's toughest problems. Each episode also features Zakaria leading a panel discussion and interviewing a major world figure.Jeh Johnson, the former U.S. Secretary of Homeland Security, joins the show this week to talk about the migration crisis as American authorities lose an important tool to keep order at the U.S./Mexico border. Then, The Economist's Mian Ridge explains Britain's highly controversial immigration bill, which would ban migrants arriving via boat. Hear why she believes it is not the right solution. Fareed also speaks with Martin Wolf, Chief Economics Commentator for The Financial Times, in the leadup to America's debt ceiling deadline. How does this circus look from abroad? And how would a default impact the international financial system? Plus, Fawaz Gerges, Professor of International Relations at The London School of Economics, talks to Fareed about the Arab League's decision this week to welcome Syria back into the organization…and what he thinks a post-American Middle East might look like.
