In the first hundred days of Donald Trump's presidency, he promoted several policies with high efficiency and a strong style, showcasing his "America First" governing philosophy. Economically, he signed executive orders to boost American manufacturing, initiated tax reduction plans, and relaxed corporate regulations in an attempt to stimulate domestic demand and employment. At the same time, he strengthened border security, pushed for immigration restrictions, and advanced the construction of the US-Mexico border wall, sparking heated discussions both domestically and internationally. In foreign affairs, Trump displayed a tough stance, reevaluating trade agreements and military deployments abroad, altering America's traditional diplomatic strategy. While supporters believe his actions are decisive and reforms clear, critics argue that his policies are overly radical and have caused social divisions. His performance in the first hundred days is both controversial and marks the beginning of a completely new political style.
