2025 National Security Strategy: Washington signals intent to reshape Europe’s political landscape to consolidate defense and economic Power

On December 4, 2025, the White House released the U.S. National Security Strategy, a document outlining the geopolitical course of the presidential administration for Donald Trump’s second term.

The Strategy primarily serves a signaling function in a rapidly evolving environment in which allies and adversaries alike are calibrating their own policies based on expected U.S. behavior in the coming years.

It explicitly declares the exhaustion of a model in which Washington unilaterally underwrites the global order and signals a shift toward compelling allies to assume primary responsibility for their respective regions.

The document defines the transatlantic space as a critical reserve of combined economic power, technological interoperability, and defense-industrial scale—without which the United States cannot sustain simultaneous deterrence of the PRC in the Western Pacific and of the axis of autocracies across Eurasia.
