Strategic Implications of the 2025 U.S. National Security Strategy | Policy Analysis 2026/01
Power, Selectivity, and the Risks of a Narrowed American Role
Executive Summary
The recently published U.S. National Security Strategy (NSS 2025) is the most significant shift of the American Grand Strategy since the end of the Cold War. The Strategy’s cornerstone is the America First doctrine as it rejects decades of liberal internationalist assumptions replacing them with a sovereignty first approach to the international system. The main priority for Washington is the protection of the homeland by restoring the American industrial and military power. At the same time, Washington is not interested in the promotion of universal norms and seeks the reduction of the costly foreign entanglements.
The 2025 NSS highlights the restraint and the selective interference abroad but also underlines the willingness to employ decisive force every time the core U.S. interests are at stake. The latter is evident especially in the Western Hemisphere, where the U.S. openly revived a modern and more strict version of the Monroe Doctrine logic. The recent U.S. military operation in Caracas, the capital city of Venezuela, and the capture of President N. Maduro illustrates how this approach blends non interventionist rhetoric with assertive regional enforcement.
This paper suggests that the 2025 NSS reflects a fundamental strategic shift as the U.S. is preparing to operate withing a global disorder defending its own interests which include border control, economic independence and internal cohesion. This strategic shift has its own risks which include alliance strain, legal contestation, regional fragmentation, and erosion of international norms.
Strategic Context
The recent publication of the 2025 NSS under President D. Trump marks a shift in how Washington perceives its own role in the international system. The NSS 2025 does not seek to defend or reform the liberal order as it does not serve anymore the American interests.
More specifically, the NSS 2025 criticizes the post-Cold War U.S. foreign policy. It’s main argument is that the United States have overextend itself by attempting to manage global issues which were not entirely related to its own national security. Humanitarian interventions, the democratic promotion, climate diplomacy and multilateral governance are portrayed as distractions that actually weakened American power and sovereignty.
That said, the NSS 2025 gives a narrower definition of national interest. National security is not defined by forward presence or alliance leadership but by controlled over supply chains, energy resources, technological innovation and of course borders. In this context, power should be used only selectively in forms of decisive deterrence, coercive diplomacy and fast dealmaking.
The NSS suggests that the international system has already entered a multipolar phase which is characterized by instability, contested norms, and declining institutional authority. In this context, the NSS argues, survival and resilience matter more than legitimacy or consensus.
