Donald Trump’s global trade war is facing increasing challenges, a year and a half after his self-proclaimed “Liberation Day” aimed at reshaping international trade. While Trump successfully negotiated more favorable conditions from Europe and other nations through tariff threats, his broader strategy is now weakened. A recent Supreme Court decision six months ago, which cancelled a significant portion of the tariffs, has significantly undermined his approach. The renewed trade dispute with Canada further complicates the situation. The ruling casts doubt on the long-term viability of Trump's tariff-centric policies. This setback raises questions about the future direction of U.S. trade relations and the president’s ability to maintain control over trade negotiations.
