The guest was one of the authors of The Rivalry Peril: How Great-Power Competition Threatens Peace and Weakens Democracy. On the strength of that interview, I think that's probably a very good book too. But it's so much about things I already believe that I'm not putting it on my own wishlist. I only manage to get through 1-2 nonfiction books a year, need to save that for things that aren't just going to be making me feel clever by confirming my existing beliefs.
