2025 ushers in one of the most dangerous periods in world history — on par with the 1930s and early Cold War, says Ian Bremmer, president and founder of Eurasia Group and GZERO Media. Highlighting the top geopolitical risks for the year ahead, Bremmer explores the impact of Donald Trump’s return to power in the US, the breakdown of the US-China relationship, the consequences of a rogue Russia, the future of unchecked AI development and more, plus some bright spots amid these unprecedented challenges.
