Trump tariff liberation means endless complication

Donald Trump is calling it Liberation Day. The president claims prospective tariffs on trillions of dollars of U.S. imports, which he is preparing to reveal on Wednesday, will mark the moment that global trading partners stop taking advantage of the United States. In fact, the decision could kick off a series of retaliations and negotiations which will drag on for years. Trump’s devotion to using tariffs to attack a vast array of American woes and foes means trade uncertainty is here to stay.
