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.This week Fareed hosts a panel on Russia with Puck's founding partner and Washington Correspondent Julia Ioffe and Russian investigative journalist Andrei Soldatov. They discuss the power dynamics between Putin, the Russian military, and mercenary leader Yevgeny Prigozhin, as well as what the impending Ukrainian counteroffensive could mean for this war. Keyu Jin, a professor of economics at LSE, joins the show to talk about her recent book, "The New China Playbook," and what she says Westerners don't understand about the Chinese economy. Plus, author Simon Winchester speaks with Fareed about human knowledge…and what effect those supercomputers in our pockets - smartphones - have had on our brains.
