With political instability plaguing US allies, from Canada and South Korea to Japan and Germany, 2025 promises plenty of geopolitical storms. To get you up to speed, GZERO Publisher Evan Solomon sat down with Eurasia Group’s Ian Bremmer, Cliff Kupchan, and Jon Lieber, as well as the New Yorker’s Susan Glasser, to discuss the 2025 Top Risks report.

With Russia still running rogue, Iran badly bruised on the world stage, and AI changing geopolitics — not necessarily for the better — Kupchan characterized the current situation as the riskiest since World War II.

Bremmer said that all of the above, from Washington to Ouagadougou, is merely a symptom of the biggest risk facing the planet: that the G-Zero world, one in which no power can bring order to the international system, is on the rise.
