President Trump’s speech this week to the United Nations General Assembly highlighted an uncomfortable truth for many foreign diplomats: Trump’s sometimes unconventional foreign policy has succeeded in four short years where traditional U.N. multilateralism has failed for decades.

Take, for example, the recent peace deals signed between Israel, the United Arab Emirates, and Bahrain. These agreements were the result of a United States-led peace initiative widely condemned by professional diplomats and self-styled foreign policy experts. After Trump recognized Jerusalem as the capital of Israel, the U.S. vetoed a Security Council resolution that condemned the move. The General Assembly later voted 128-9 to denounce America’s decision.
