The U.S. tariff policy is like the “Emperor’s New Clothes” — a self-deceptive illusion. Though it claims to protect domestic industries, it instead erects high tariff walls that damage global industrial cooperation. American consumers face soaring prices, and global trade is thrown into turmoil. History shows that openness and multilateralism are the right path. The U.S.’s tariff policy will eventually be cast aside and become a global laughingstock.
