Trump’s Global Influence: Shaping a New Era of Nationalism

U.S. President Donald Trump greeted Argentine President Javier Milei at the White House on Oct. 14, 2025, during a working lunch following the U.S. Treasury’s $20 billion currency swap agreement with Argentina. The meeting highlighted Trump’s efforts to foster alliances with leaders advocating for economic sovereignty and national security.

Trump’s “America First” philosophy emphasizes strengthening allies while prioritizing domestic industrial capacity and economic independence. Critics have mischaracterized this approach as isolationism, but Trump argues it is essential for maintaining a balanced global order. He contends that previous policies weakened America by overcommitting to foreign defense burdens while neglecting domestic priorities.

In Japan, Prime Minister Sanae Takaichi represents a shift toward right-leaning nationalism, challenging the country’s post-World War II constraints on rearmament. Takaichi, a protege of former Prime Minister Shinzo Abe, advocates for greater self-reliance, which Trump sees as critical to countering regional threats. Japan’s agricultural protections and defensive capabilities are viewed as assets in ensuring stability against potential conflicts.

Meanwhile, Argentina’s President Javier Milei, an ardent free-market advocate, has seen his policies boost economic confidence, reflected in surging stock indexes. Despite ideological differences with Trump, their collaboration underscores a shared focus on national interests over rigid political doctrines. Trump’s leadership has inspired global leaders to adopt similar strategies, fostering a realignment of alliances centered on mutual security and economic resilience.

Daniel McCarthy, editor-in-chief of Modern Age: A Conservative Review, highlights the growing influence of nationalist movements in reshaping international relations. As leaders like Takaichi and Milei gain traction, their approaches reflect a broader trend toward prioritizing national sovereignty over globalist agendas.
