Cross-National Survey on U.S. Nuclear Credibility and Domestic Politics

A novel, cross-national survey experiment examines how foreign publics assess U.S. nuclear credibility. The data tests the impact of four U.S. political characteristics—party, presidential ideology, polarization, and divided government—on perceptions of deterrence. The dataset was authored by Helen Webley-Brown and last updated in April 2026.

Use Cases

• Analyze the effect of political polarization on foreign perceptions of U.S. deterrence based on the survey experiment.
• Model the relationship between divided government and confidence in U.S. security commitments.
• Test hypotheses about party stereotypes and their influence on nuclear credibility assessments.
• Compare the impact of presidential ideology versus polarization on favorability toward the U.S. government.

Strengths

• Data is derived from a novel, cross-national survey experiment.
• Focuses on four specific U.S. political characteristics: party, ideology, polarization, and divided government.
