How U.S. Unpredictability Is Reshaping European Strategy

Key Insights
  • Main question: How has the EU responded to perceived unpredictability in U.S. foreign policy under the Trump administration?
  • Argument: Unpredictability erodes credibility, generating alliance uncertainty incentivizing allies to diversify partnerships rather than abandon existing alliances.
  • Conclusion: In response to unpredictability in U.S. foreign policy, the EU has not abandoned the transatlantic alliance but has instead diversified its partnerships and developed limited strategic autonomy.
