The Center for a New American Security’s Energy, Economics, and Security (EES) Program designed and conducted an economic wargame to explore possible pathways to resolve the trade wars sparked by historic levels of U.S. tariff escalation. This trade wargame was designed to examine foreign government responses to U.S. tariffs, including whether they would retaliate, negotiate, and/or make concessions. After being punished by U.S. tariffs, would foreign governments have the appetite to engage in dealmaking with the United States and, if so, under what conditions? The trade wargame was conducted on March 17, 2025, two weeks before President Donald Trump made his real-world announcement of shockingly high tariff rates on a day he deemed “Liberation Day.”
