The Knot
To many, Russia, and the wider Eurasia, is a riddle, wrapped in a mystery, inside an enigma. But it doesn’t have to be. The Eurasian Knot dispels the stereotypes and myths about the region with lively and informative interviews on Eurasia’s complex past, present, and future. New episodes drop weekly with an eclectic mix of topics from punk rock to Putin, and everything in-between. Subscribe on your favorite podcasts app, grab your headphones, hit play, and tune in. Eurasia will never appear the same. Hosted on Acast. See acast.com/privacy for more information.
