POLITICAL SCIENCE · INTERNATIONAL SECURITY
A new cross-national survey experiment reveals how U.S. domestic political turmoil directly undermines America’s nuclear credibility abroad. Researchers found that political polarization—not party control or presidential ideology—significantly reduces foreign publics’ confidence in U.S. extended deterrence commitments. For a retired public servant and writer attuned to the fragility of democratic institutions, this study offers a sobering empirical account of how domestic discord can erode a nation’s standing in the highest-stakes arena of international security.
