We are kicking off 2025 by looking at some of the biggest geopolitical risks coming down the pike, from Trump's return to the White House, the tariff wars, our worsening U.S.-China relationship, and conflicts in Ukraine and the Middle East. What will end up being the biggest risk in 2025? Here's our hot take: It won't be Trump, though he's a symptom. The biggest risk of 2025 is that this becomes the year the G-Zero wins. As longtime fans surely know, the G-Zero world is when no one power or group of powers is willing and able to drive a global agenda to maintain international order. We have lived with this lack of international leadership for nearly a decade. But in 2025, the problem will get a lot worse.
