When the United States openly pressured Denmark over Greenland, the immediate dispute faded fast. The damage to trust did not.

This episode looks beyond Greenland to a bigger question: what happens when the world’s most powerful country starts behaving like an unreliable partner? International law, trade agreements, and security alliances only work if states believe others will still play by the rules when it no longer suits them. That belief is now under strain.

With Gregory Shaffer, Scott K. Ginsburg Professor of International Law at Georgetown, we talk about power, coercion, and the quiet erosion of trust in international treaties. Is the U.S. still seen as a credible partner? Are rules giving way to pressure politics? And are we already sliding into a global order where raw power matters more than promises? This is not just a diplomatic story. It may be a systemic risk.
