From continental consolidation to global primacy—and now to strategic recalibration.
This article examines how U.S. grand strategy evolved from nineteenth-century isolation to post-1941 interventionism and argues that the National Security Strategy 2025 marks a structural adjustment toward restraint, selective primacy, and network-based power amid intensifying great-power competition
Abstract
This article traces the evolution of U.S. grand strategy from continental consolidation in the nineteenth century to post-1941 global engagement, culminating in the pragmatically calibrated approach articulated in the U.S. National Security Strategy 2025 (NSS 2025). It argues that while nineteenth-century isolationism and non-interventionism prioritized continental security and limited external commitments, post-1941 strategy institutionalized global leadership and structural intervention. NSS 2025 synthesizes these historical lessons by balancing selective global engagement, allied burden-sharing, and technological-economic resilience in response to contemporary great-power competition. The strategy demonstrates continuity in U.S. engagement while introducing adaptive mechanisms designed to limit overextension and enhance strategic sustainability in a multipolar and technologically contested environment.
Keywords: U.S. grand strategy; isolationism; interventionism; NSS 2025; great-power competition; strategic recalibration.
1. Continental Isolation and Non-Interventionism (1848–1941)
The decisive structural turning point in early U.S. grand strategy occurred in 1848 with the Mexican Cession, which completed continental consolidation and removed the most immediate external territorial threats to the United States. With the continental project effectively concluded, the marginal strategic utility of further territorial expansion declined sharply, while its political, demographic, and governance costs became increasingly evident. Expansion no longer promised clear security dividends and instead exposed the republic to internal instability, governance challenges, and sectional conflict.
In this context, isolationism and non-interventionism emerged not as ideological preferences but as rational strategic responses to favorable geography and limited external threat vectors. U.S. security rested primarily on continental depth, maritime access, and economic growth rather than forward military presence or permanent alliances. As Posen argues, restraint can constitute a coherent grand strategy when geography, power asymmetries, and threat environments allow a state to limit commitments without jeopardizing security (Posen, 2014). This logic shaped U.S. strategic behavior through the early twentieth century, producing a pattern of selective engagement, episodic intervention, and systematic avoidance of binding security obligations.
2. Global Engagement and Structural Intervention (Post-1941)
The attack on Pearl Harbor in December 1941 exposed the limitations of continental insulation in an era of industrialized warfare and systemic interdependence. Geographic distance could no longer guarantee security once global supply chains, alliance systems, and ideological conflicts became structurally linked to U.S. prosperity and survival. From this point onward, American security became inseparable from the stability of the international order itself.
Postwar U.S. strategy institutionalized global engagement through permanent alliances, overseas basing, and leadership in multilateral institutions. Interventionism evolved from an episodic policy instrument into a structural condition of American primacy. During the Cold War, the United States assumed the role of systemic guarantor, shaping regional balances of power and underwriting collective security across Europe and Asia. As Brooks and Wohlforth emphasize, U.S. primacy rested not only on material superiority but also on a sustained willingness to bear the political, military, and economic costs of global leadership (Brooks & Wohlforth, 2016).
This strategic model persisted after the Cold War, even as threat conditions evolved and the costs of prolonged military engagements increased. By the early twenty-first century, tensions between expansive global commitments and domestic political tolerance for intervention had become increasingly pronounced.
3. Pragmatic Recalibration: NSS 2025
The U.S. National Security Strategy 2025 reflects a pragmatic recalibration rather than a rejection of post-1941 global engagement. It explicitly acknowledges the strategic and political limits of open-ended intervention while reaffirming the necessity of sustained international involvement under conditions of renewed great-power competition. In this sense, NSS 2025 incorporates elements of Trump-era skepticism toward costly and indefinite foreign commitments but reframes them within a more institutionalized and strategically disciplined framework.
Central to the strategy is an emphasis on national sovereignty, infrastructure protection, and economic resilience as foundational sources of power. NSS 2025 prioritizes secure supply chains, energy security, and technological leadership as prerequisites for strategic autonomy. Rather than treating domestic resilience as separate from foreign policy, the strategy integrates internal capacity with external influence, reflecting a broader turn toward geo-economic statecraft.
This orientation aligns closely with Farrell and Newman’s argument that power in the contemporary international system increasingly derives from control over key nodes in global economic and technological networks. States occupying central positions in financial, production, and innovation systems can convert interdependence into durable sources of coercive leverage without resorting to territorial control (Farrell & Newman, 2019). NSS 2025’s focus on semiconductors, critical minerals, infrastructure security, and financial architecture reflects this logic of network-based power.
At the same time, NSS 2025 places renewed emphasis on allied burden-sharing and partner empowerment, particularly in Europe and the Indo-Pacific. Rather than seeking unilateral dominance, the strategy stresses adaptive leadership and coalition management. This approach corresponds to Drezner’s analysis of crisis governance and international order, which emphasizes that durable systems depend less on coercive enforcement than on the capacity of leading states to adapt rules and expectations in cooperation with others (Drezner, 2019).
The strategy also advances a model of selective primacy. U.S. commitments are prioritized toward high-impact domains—such as artificial intelligence, advanced manufacturing, space, and strategic technologies—while exposure to open-ended military interventions is deliberately constrained. This reflects continuity with Trump-era restraint while embedding it within a broader logic of alliance-based deterrence and networked competition.
4. Historical Continuity and Strategic Implications
Taken together, U.S. grand strategy can be understood as evolving through three broad phases: continental isolation and restraint (1848–1941), structural global engagement (post-1941), and pragmatic recalibration in the mid-2020s. NSS 2025 preserves the core commitment to global engagement while recalibrating its scope, instruments, and priorities to address the risks of overextension and domestic political fatigue.
Positioned between restraint, selective primacy, and networked power, NSS 2025 represents a hybrid strategic model. It neither abandons leadership nor embraces maximalist interventionism. Instead, it advances an approach in which resilience, allied capacity, and control over critical networks function as the primary mechanisms for sustaining U.S. influence in an increasingly contested international system—reflecting both historical continuity and strategic adaptation.

Большое спасибо автору. Глубокая и аргументированная статья, раскрывающая новую стратегию США в историческом и геостратегическом аспектах. Если позволительно, несколько вопросов и замечаний.
Представляется, что стратегия США до 1941 г. была основана на наличии пространства для экспансии внутри Америки (вначале — земли на Западе, Юге и Севере территории современных США) и ресурсов, которыми страна располагала на тот момент для осуществления такой экспансии. В этой связи термин «изоляционизм» применительно к политике США до начала XX века, на мой взгляд, следует использовать весьма условно. Став экономически ведущей державой мира к началу XX века, США начали расширять экспансию, прежде всего в Центральную и Латинскую Америку, Юго-Восточную Азию и Тихоокеанский регион, избегая при этом прямого столкновения с интересами Великобритании, Франции и Германии на других континентах. С начала XX века, по-видимому, корректнее говорить уже не об изоляционизме, а о сочетании ограниченного невмешательства с политикой активного влияния, поскольку США в этот период обладали как значительными экономическими интересами, так и военно-политическими возможностями для различных вариантов действий.
Атака японских сил на Пёрл-Харбор произошла на фоне ресурсной блокады, введённой США в отношении Японии. В свою очередь, эта блокада стала результатом активного участия США в борьбе за контроль над сырьевыми ресурсами Дальнего Востока и Юго-Восточной Азии, начавшейся задолго до 1941 г.
В период с 1945 г. до конца 1960-х годов США в ряде регионов вытеснили прежние колониальные державы с других континентов, во многих случаях опираясь на антиколониальные движения, и заняли их место прежде всего в экономическом, а иногда и в военно-политическом отношении. Как показал опыт Вьетнама, такая замена оказалась успешной далеко не везде, особенно с учётом активного противодействия со стороны СССР и поддерживаемых им режимов.
В конце XX — начале XXI века США, по-видимому, недооценили масштаб происходящих изменений. В результате они во многом сами способствовали формированию конкурента и потенциального противника в лице коммунистического Китая, который к 2025 г. жёстко конкурирует с США в экономической и политической сферах по всему миру. Насколько действия (а не декларации о противодействии китайской угрозе) со стороны администрации Трампа, отражённые в Стратегии 2025 г., соответствуют реальному характеру этой угрозы?
В своё время Барак Обама назвал Владимира Путина лидером «региональной державы». Последующие события показали, что, помимо личного оскорбления Путина, такая оценка отражала недооценку роли Российской Федерации как соперника США глобального масштаба. Не заложена ли и в Стратегии 2025 г. аналогичная ошибка в оценке роли России в международной политике?

Many thanks to the author. This is a profound and well-argued article that elucidates the new U.S. strategy in its historical and geostrategic dimensions. If I may, I would like to offer several questions and observations.
It appears that U.S. strategy prior to 1941 was based on the availability of space for expansion within the Americas (initially lands in the West, South, and North of what is now U.S. territory) and on the resources the country possessed at that time to carry out such expansion. In this regard, the term “isolationism,” when applied to U.S. policy before the early twentieth century, should, in my view, be used only with considerable qualification. Having become the world’s leading economic power by the beginning of the twentieth century, the United States began to expand its reach primarily into Central and Latin America, Southeast Asia, and the Pacific region, while avoiding direct clashes with the interests of Great Britain, France, and Germany on other continents. From the early twentieth century onward, it seems more accurate to speak not of isolationism, but of a combination of limited non-intervention with a policy of active influence, since during this period the United States possessed both significant economic interests and the military-political capabilities to pursue various courses of action.
The Japanese attack on Pearl Harbor occurred against the backdrop of a resource blockade imposed by the United States on Japan. This blockade, in turn, was the result of active U.S. involvement in the struggle for control over raw material resources in the Far East and Southeast Asia, which had begun long before 1941.
From 1945 until the late 1960s, the United States displaced former colonial powers in a number of regions on other continents, in many cases relying on anti-colonial movements, and took their place primarily in economic—and sometimes also in military-political—terms. As the experience of Vietnam demonstrated, this substitution was far from successful everywhere, especially given the active opposition of the USSR and the regimes it supported.
At the turn of the late twentieth and early twenty-first centuries, the United States appears to have underestimated the scale of the changes taking place. As a result, it largely contributed itself to the emergence of a competitor and potential adversary in the form of communist China, which by 2025 is competing fiercely with the United States in economic and political spheres worldwide. To what extent do the actions (as opposed to declaratory statements about countering the Chinese threat) of the Trump administration, as reflected in the 2025 Strategy, correspond to the real nature of this threat?
At one time, Barack Obama referred to Vladimir Putin as the leader of a “regional power.” Subsequent events showed that, beyond personally offending Putin, this assessment reflected an underestimation of the role of the Russian Federation as a global-scale rival to the United States. Does the 2025 Strategy also contain a similar error in assessing Russia’s role in international politics?
Dear Boris Filanovsky,
