The Principle of “Peace Through Strength” in the United States’ National Security Strategy of November 2025

By Jean Venel Casseus

In its National Security Strategy document published in November 2025, the American administration brings the principle of “Peace Through Strength” back to the forefront. The idea seems simple, but it takes on new significance in this text which reorganizes the country's priorities, clarifies expectations of allies, and redefines the place of the United States on the world stage. According to the document, peace results neither from goodwill nor strategic delegation, but from assumed, visible, and credible power.

The 33-page text first describes a break with what it presents as errors accumulated since the end of the Cold War: excessive extension of American commitments, disproportionate reliance on international institutions, complacency towards uncooperative partners, and economic openness that weakened national industry. In this context, “Peace Through Strength” is presented as a structured response to these decades of strategic dispersion. The objective is to re-establish a deterrence capability strong enough to prevent conflicts before they arise, based on the idea that adversaries avoid confrontation when they know they cannot bear the costs.

The strategy emphasizes the combination of military power, economic vitality, and technological advancement. Strength is measured not only by armaments but also by industry, energy, scientific research, and diplomacy. With a robust economy, sustained reindustrialization, increased energy mastery, and asserted leadership in strategic technologies, the United States affirms in the document that it possesses the necessary means to impose peace in the world. A nation equipped with powerful tools preserves its room for maneuver and limits the recourse to armed confrontation, the authors note. Power opens possibilities for agreements, closes the path to prolonged crises, and imposes compromises on actors drawn to escalation, according to the analysis put forward by the Trump administration.

The document cites the recent resolution of several international crises as an illustration of this approach. In this logic, the stronger the American position, the broader the negotiations. Force does not extinguish tensions, but it reduces the temptation for actors to test American limits, according to the officials who participated in the drafting. This same logic structures relations with allies. Washington maintains existing partnerships but demands increased effort. NATO must achieve a new defense spending target set at 5% of GDP. The Indo-Pacific requires reinforced involvement from Japan, South Korea, or Australia. “Peace Through Strength” thus relies on a clearer sharing of responsibilities.

The principle then organizes the regional interpretation of American policy. In Latin America, it serves to counter cartels, limit massive migrations, and reduce the influence of foreign powers in the hemisphere, according to the stated objectives. In Asia, it aims to prevent a confrontation around Taiwan and maintain open trade routes in the face of Chinese ambitions. In Europe, it intends to promote the stabilization of the continent, encourage a rapid resolution to the war in Ukraine, and strengthen the strategic autonomy of Western bloc countries. In the Middle East, it relies on a strong but targeted American presence to limit Iranian influence and encourage new diplomatic normalizations. In Africa, it supports a transition from an aid model to an investment model, with particular attention paid to strategic resources and essential infrastructure, according to the priorities put forward in the text.
