Prologue: Two strategies, two Americas

Reading the United States’ National Security Strategy isn’t just about understanding its foreign policy doctrine; it’s about understanding how the American superpower seeks to shape itself. Biden’s 2022 NSS and Trump’s 2025 NSS are not merely two variations of the same theme; they are two different worldviews stemming from two visions of America. In 2022, the idea is that the international order remains protectable and can be updated through coalitions, rules, institutions, and integrated deterrence. In 2025, the outlook is almost opposite: the U.S. made a mistake by trying to manage everything without a clear hierarchy of priorities, and national security now focuses on the selective defense of vital interests, with sovereignty and internal capacity as its foundation.

The fracture, therefore, is not simply between “interventionism” and “isolationism.” It exists between two models of dominance. One is architectural, designed to create systemic predictability. The other is transactional, focused on avoiding overstretch by selecting issues and sharing costs through contracts. Somewhere in between, there is a historical reality that both approaches acknowledge, each in its own way: America can no longer sustain the same level of global commitments without facing domestic political and social costs.

2022: Order as a power multiplier

The 2022 NSS is centered on a powerful, almost identity-level idea: American power is not only material but relational. Alliances and partnerships are shown as a competitive edge that adversaries cannot duplicate; competition with China is described as the “pacing challenge,” while Russia is viewed as an immediate threat, intensified by the war in Ukraine.

The core idea is integrated deterrence across military, technological, economic, diplomatic, and industrial spheres. Beneath that lies a core belief — rooted in the American liberal-internationalist tradition — that if the United States invests in Western unity and bolsters domestic capabilities, it can still shape the international environment and reduce systemic uncertainty. This reflects an America that, even while acknowledging great-power competition, continues to support a rules-based order.

Within this framework, Ukraine is not a secondary issue; it acts as the test case for the principle that aggression should not be rewarded and that territorial sovereignty is a core norm. The document does not present this commitment as opportunistic; instead, it shows it as structural: if the wall collapses here, the cost of deterrence will inevitably rise elsewhere.

2025: Security as selective sovereignty

The 2025 NSS, by contrast, is based on a controversial diagnosis: for decades, the United States was supposedly pulled into a “priority-less” strategy, an operational universalism that scattered resources, encouraged allies’ free-riding, and weakened the domestic industrial and social foundations. The document emphasizes hierarchy: you cannot be everywhere, and you should not treat every region and every problem as equally important.

That diagnosis influences its grammar. National security is directly linked to borders, cohesion, industry, energy, resilience, technological dominance, and deterrence, framed in a tone that combines geopolitics with an internal culture war. The approach is formally defined as “America First” and presents itself as a “flexible” realism: cooperate when it benefits, avoid interventions likely to become ongoing, leverage economic and technological tools as sources of power, and — most importantly — shift the costs of security onto a network of partners, but in a conditional, contractual manner.

The most notable shift is elevating the Western Hemisphere to the top-priority theater, with a “Trump Corollary” to the Monroe Doctrine: the idea that the United States must reassert its dominance in its regional sphere, prevent extra-hemispheric powers from controlling strategic assets, and employ economic, diplomatic, and even military means to combat cartels, migration, and foreign influence. Here, foreign policy ceases to be distant: it becomes border geopolitics.

The real axis of comparison: coalition of order versus diplomacy of contract

The most significant difference between 2022 and 2025 lies in the implicit theory of international coordination. In 2022, American leadership reduced coordination costs by offering frameworks, public goods, and predictability. By 2025, American leadership aims to cut direct material costs by increasing conditionality: burden-sharing and burden-shifting become a core principle rather than just a theme.

This is where the comparison shows what is really at stake. A “rules-based” order depends on trust and commitment; a “contract-based” order relies on aggressive deterrence, exchange, and pressure. The first tends to stabilize the environment but requires long-term dedication; the second can deliver quick results but risks heightening volatility and prompting allies to hedge, protecting themselves from American uncertainty.

Ukraine: in 2022 the symbol of order; in 2025 the cost of overstretch

The Ukraine dossier remains the clearest fracture point. In the 2022 NSS, the war in Europe acts as a test of the system and Western credibility; NATO structure and transatlantic unity are part of a strategic response. In the 2025 NSS, the focus shifts toward quick stabilization: ending hostilities and preventing escalation are seen as core interests, partly because prolonged involvement in Europe is viewed as diverting resources and attention from other theaters deemed more critical.

This isn’t just a matter of preference; it’s a difference in the nature of the risk. In 2022, the risk involves normalizing territorial coercion; by 2025, the danger is being caught in a strategic periphery while domestic constraints worsen and competition with China demands attention.

China and Taiwan: the constant that changes shape

China remains consistent across both documents, but how it is described — and confronted — varies. In 2022, competition is systemic and multidimensional, involving alliances, technology, industry, and diplomacy within a “free and open” order framework; deterrence is integrated, and the allied network serves as the key multiplier. By 2025, the focus shifts to a more openly geo-economic and industrial approach: supply chains, materials, energy, tariffs, reciprocity, and technological dominance are prioritized as main tools, and allies are urged to “do much more” to convert regional posture into tangible capability.

Taiwan is the point where deterrence can no longer remain merely rhetorical in both strategies. However, here the operational paradox of the 2025 posture emerges: credible deterrence requires predictable commitment, but transactional diplomacy tends to make every compromise negotiable, and thus more ambiguous. This is where the “dossier-by-dossier” approach risks incurring a strategic cost: making allies’ hedging rational.

Europe: from strategic community to conditional partner

In 2022, Europe is primarily defined by architecture: NATO, interoperability, cohesion, shared political capital. By 2025, Europe becomes a focus of negative civic and cultural judgment: regulation, migration, free speech, identity, and defense capacity are seen as factors that weaken the European partner and justify an increasingly conditional relationship.

This shift is geopolitically significant because it politicizes the alliance on levels that go beyond traditional security. Sociologically, it signals a transformation of the alliance from being merely an institution to becoming a discourse centered on identity: Europe is no longer just a vassal; it becomes a symbolic space where America redefines itself.

Middle East: hidden continuity and a difference in style

Paradoxically, in the Middle East, the two documents share a similar goal: avoiding the cycle of endless wars and minimizing direct commitments. The difference lies in how they present their narratives. In 2022, reduction is pursued through risk management and coalitions, using order and partnerships as containment tools. By 2025, it is based on a logic of negotiated peace as a form of realignment: “closing” conflicts to free up resources, harvest economic benefits, and reduce strategic friction.

The continuity in both documents is “hegemonic fatigue”; the difference is the political form used to manage that fatigue. In 2022, it is framed as a responsibility to maintain order; in 2025, as selective sovereignty.

Climate and energy: a reversal that signals a clash of visions

The comparison becomes illustrative when discussing climate and energy. In 2022, climate is regarded as a security issue and a realm of leadership and cooperation, connected to resilience, innovation, and global credibility. By 2025, the focus shifts to energy dominance and a critique of “Net Zero” ideologies, viewing energy as a means for power and competitiveness.

This change is not just about the environment; it reflects the evolving shape of Western consensus. In 2022, climate cooperation might have served as transatlantic glue; by 2025, it could become a fault line with regulatory Europe and parts of the “Global South” that interpret the transition differently.

The historical significance of the shift: from architectural hegemony to transactional hegemony

Taken as a whole, the comparison between 2022 and 2025 illustrates a shift in American hegemony. In 2022, the United States still attempts to manage competition by establishing frameworks: using order as a tool of power and foresight. By 2025, America acknowledges — or claims — that power and foresight are too costly, and that the priority is safeguarding the core: borders, industry, energy, cohesion, and a “secured” Western Hemisphere as a strategic rear area.

The geopolitical consequence is mixed. On one hand, selection can lessen overstretch and help shift resources toward the main competition with China. On the other hand, leadership based on contracts and dossiers often increases systemic uncertainty by making allies’ expectations less automatic and encourages rivals to test boundaries.

Epilogue: strategy as a reflection of cohesion

The final point is the most unsettling and also the most real: both NSS documents, through different paths, acknowledge that American foreign policy is increasingly intertwined with domestic politics. In 2022, internal cohesion is the foundation of leadership for order; by 2025, cohesion becomes the core of national security and the basis for decision-making. This is the real geopolitical key to the comparison: not only is the world changing, but the way the United States engages in the world is evolving. 2022 attempts to repair the existing structure; 2025 seeks to redefine the hierarchy. History will decide whether that hierarchy creates stability or ushers in a period where America, still incredibly powerful, is seen as more unpredictable. And in the international system, a superpower’s unpredictability is never neutral: it becomes a space that others learn to control.
