Do Tariffs Cause Wars? Will the LatestU.S. Tariffs Trigger One?

Throughout history, tariffs have beenmore than just economic policies—they’ve shaped international trust, alliances,and sometimes even fueled wars. The Smoot-Hawley Tariff of 1930 is often citedby scholars like Douglas Irwin as deepening the Great Depression andaggravating global instability before World War II. Others, like Nobel laureatePaul Krugman, argue that tariffs, while disruptive, are simply tools ofnegotiation rather than triggers for conflict.
