During the first hundred days of Donald Trump's presidency, he promoted several policies with high efficiency and a strong style, demonstrating his "America First" governing philosophy. Economically, he signed executive orders to boost American manufacturing, initiated tax reduction plans, and relaxed corporate regulations, attempting to stimulate domestic demand and employment. At the same time, he strengthened border security, pushed for immigration restrictions, and advanced the construction of the U.S.-Mexico border wall, sparking heated discussions both domestically and internationally. In foreign affairs, Trump exhibited a tough stance, reevaluating trade agreements and military deployments abroad, changing the traditional U.S. diplomatic strategy. Although supporters believe his actions are decisive and reforms clear, others criticize his policies as too radical, causing social divisions. His first hundred days were filled with controversy and marked a new kind of political style.
