特朗普换“马甲”重启15%关税，硬指美国爆发“收支危机”遭经济学界反驳

Group 1 - The Trump administration has imposed a 15% tariff on imported goods under the guise of a "temporary substitute measure" to address a non-existent "U.S. international balance of payments crisis" following a Supreme Court ruling that invalidated previous tariffs [1][2] - The new tariff policy, effective immediately, replaces a previous range of tariffs of 10%-50% and is based on the Trade Act of 1974, which has never been used before [1][5] - Economists, including former IMF officials, argue that the claimed "balance of payments crisis" does not exist, as the U.S. current account deficit remains manageable and does not meet the legal criteria for such a crisis [2][3] Group 2 - Legal experts indicate that the use of Section 122 of the Trade Act may face challenges, as the Department of Justice previously stated that this section is not appropriate for addressing trade deficits [5][6] - The legal basis for the tariffs is questioned, with concerns that the Trump administration's interpretation of the law could lead to lawsuits [6] - The Liberty Justice Center, which has previously challenged tariffs, is monitoring the situation closely for potential legal actions regarding the new tariffs [6]
