关税刚被判定违法，特朗普就代表美国，对全球打响第一枪

Group 1 - The U.S. Supreme Court ruled that the Trump administration's use of the International Emergency Economic Powers Act to impose global tariffs was unconstitutional, requiring congressional authorization for tax policies [1][3] - This ruling undermines Trump's previous hardline stance on tariffs, which he used as a tool for diplomatic leverage against countries like China, Mexico, and Canada [1][3] - Trump's immediate response was to sign a new tariff law, challenging the Supreme Court's decision and indicating a political struggle, while also criticizing the conservative justices who overturned his policies [3][5] Group 2 - The new tariff policy is expected to lead to economic shocks, including rising global commodity prices and increased production costs for businesses, which could severely impact consumer purchasing power [5] - The long-term implications of Trump's tariff policy may negatively affect the U.S.'s leadership position in global trade, as the ability to impose tariffs as a negotiation tool is diminished [5][7] - The current global economic landscape emphasizes cooperation and dialogue over unilateral actions, suggesting that Trump's approach may be misaligned with future economic development strategies [7][8]
