Trump Shifts US Strategy Toward Regional Influence and Mediation

In 2025, Donald Trump transitioned United States foreign policy from global leadership toward a strategy focused on national interests and regional privilege. This shift was codified in December through a new National Security Strategy that cast the US as a mediator rather than a belligerent in the conflict between Russia and Ukraine. To implement this role, the administration hosted a summit in Alaska to open diplomatic channels, while simultaneously demanding payment for military aid and slowing sanctions against Russia.

This pivot caused a rupture in Euro-Atlantic relations, as the European Union continued to provide unconditional support for Ukraine and implemented three additional sanctions packages against Moscow. Simultaneously, the US launched a global trade war against more than seventy countries, including the European Union, triggering retaliatory export controls on rare-earth metals from China.

The National Security Strategy also formally revived a reinterpretation of the Monroe Doctrine, designating the Western Hemisphere as a primary US sphere of influence. This new framework intensified pressure on Venezuela and identified Canada, the Panama Canal, and Greenland as areas of special strategic concern. To pursue these regional goals, Trump appointed Louisiana Governor Jeff Landry as US Special Envoy for Greenland with a mandate to bring the autonomous Danish territory into the United States, a move that sparked outrage from the Government of Denmark.
