Core Viewpoint - The U.S. is shifting its global strategy, moving away from being a global leader and adopting a more isolationist approach, as articulated in the National Security Strategy report released on December 9, 2025, which states, "The U.S. is no longer the Atlas supporting the world" [1][7] Group 1: Tariff Policy and Economic Impact - On April 2, 2025, President Trump announced a "Liberation Day," imposing a 10% baseline tariff on imports from most countries, with higher tariffs for those with trade deficits, particularly targeting China with tariffs as high as 60% [3][4] - The tariffs are intended to create a "physical decoupling" from China, affecting global supply chains and leading to significant price increases for American consumers [4][5] - The global stock market reacted sharply to the announcement, indicating a potential "indiscriminate attack" on the existing global trade system [3] Group 2: Strategic Shift in U.S. Foreign Policy - The National Security Strategy introduced the "Trump Doctrine," which emphasizes U.S. dominance in the Western Hemisphere and a strategic retreat from global engagement, particularly in Eurasia [7][9] - The U.S. is focusing on strengthening its control over the Americas, including renegotiating control over the Panama Canal and deploying advanced missile defense systems domestically [7] Group 3: Reactions from Global Leaders - European leaders expressed strong concerns over the U.S. shift, with calls for increased European defense capabilities to address geopolitical risks [9][11] - In Asia, the U.S. is adopting an "outsourcing defense" strategy, requiring allies like Japan and South Korea to bear more military costs and enhance their military presence [9][11] Group 4: Economic Consequences and Global Responses - The IMF projected that the global tariffs initiated in April 2025 could lead to a cumulative loss of over $1.5 trillion in global GDP over three years, with small economies being the most affected [13] - European nations are accelerating defense initiatives, including a proposed "European Army" and significant investments in military capabilities [13] - In Asia, countries are emphasizing the need to maintain stable supply chains and oppose trade protectionism, as evidenced by a joint statement from RCEP members [15]
