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. Fareed offers his Take on the Johnson & Johnson vaccine pause and the damage it may have done. Then, Vladimir Putin warned the West this week not to cross Russia's "red line." What does that mean? And what to make of the massive build-up of Russian troops on its border with Ukraine? Fareed talks to Radek Sikorsky, the former Foreign Minister of Poland who has negotiated with Putin. Also: words matter. On Saturday, President Biden declared the mass killings of Armenians in WWI a "genocide," but what does that word mean? What is its history? Fareed talks to expert Philippe Sands, Professor of Law at University College London. And, after global leaders made pledges to cut emissions at a U.S.-convened climate summit this week, will developing nations follow suit? M. Sanjayan, CEO of Conservation International, weighs in. Plus, Covid's devastating comeback in India. The Guardian's Hannah Ellis-Petersen reports on the "COVID hell" that India is experiencing. And, finally, why nuclear power is the more sustainable option for the future of energy production.
