表决出炉，4票反对无效，特朗普发文怒吼：美国将成第三世界国家

Core Viewpoint - The U.S. federal court's historic ruling declared that most of the global tariff policies implemented by the Trump administration exceeded presidential authority and were illegal, causing significant political upheaval [1][3]. Group 1: Legal and Political Implications - The ruling was made by a majority of seven liberal judges, stating that Trump's unilateral imposition of tariffs on steel, aluminum, and semiconductors violated constitutional provisions [3]. - The Trump administration must appeal to the Supreme Court by October 14, as indicated by legal procedures [3]. - Trump's strong reaction to the ruling highlights the central role of tariff policies in his economic strategy, which aims to protect U.S. industries and secure votes in manufacturing states for upcoming midterm elections [4]. Group 2: Economic Impact - The Trump administration has reintroduced and expanded trade protection policies, imposing an average punitive tariff of 15% on major trading partners, including China, the EU, and Japan [4]. - Analysts warn that if the Supreme Court upholds the ruling, the U.S. could lose over $2.8 trillion in foreign direct investment and face severe disruptions in global supply chains [4]. - Current polling shows only 37% support for the existing tariff policies, with 53% opposed, largely due to rising consumer prices, including a 4.2% increase in core CPI and a 6.8% rise in food prices [6]. Group 3: International Reactions and Future Outlook - The international community generally welcomes the court's ruling, viewing it as a step towards restoring a multilateral trade system [6]. - If the Trump administration's appeal is successful, it could lead to intensified trade conflicts, while a ruling against the administration may prompt Congress to pass amendments limiting presidential tariff powers [6]. - The ongoing legal battle signifies a critical juncture for U.S. trade policy, indicating potential profound changes ahead [6].
