Would China and the U.S. go to war over Taiwan? What about China's reported test of a hypersonic missile? Fareed talks to Richard Haass, president of the Council on Foreign Relations, and Oriana Skylar Mastro of The American Enterprise Institute about the complex relationship the U.S. must navigate between China and Taiwan. Haass also reflects on the complicated legacy of his former boss at the State Department, the late Gen. Colin Powell. Then, David Sanger, national security correspondent for the New York Times, explains why China's hypersonic missile testing is a significant step towards a potential twenty-first-century arms race. As Germany bids auf wiedersehen to long-time Chancellor Angela Merkel, Kati Marton, journalist and author of the new book "The Chancellor," tells Fareed about the qualities that made Merkel such a powerful chancellor and the legacy she leaves behind. Plus, Fareed checks in with Mahbouba Seraj, the founder of the Afghan Women's Network. Seraj is still in Kabul and tells Fareed what life in the nation is like, ten weeks after the Taliban took over. Lastly, Fareed looks at what some are calling "Striketober" — the rash of strikes and other labor problems around America - and why it actually might be a net positive for labor, business, and the American economy.
