Is the study of strategy a cumulative science, building steadily toward a better understanding of how force serves political ends? Or does it lurch between competing visions of rationality, culture, technology, and material power—each framework arising in response to a specific historical predicament and never fully displacing its rivals? This tension defines strategic history, the subfield of military history that examines how thinkers, states, and military organizations have conceptualized the use of force for political objectives. Over nearly two centuries, strategic thought has produced a series of frameworks that have challenged, absorbed, narrowed, or coexisted with one another, leaving the field today in a state of productive pluralism.
The first two frameworks emerged from the Napoleonic Wars and their aftermath. Clausewitzian Strategic Theory, articulated in Carl von Clausewitz's unfinished On War (1832), treated war as a political instrument governed by a paradoxical trinity of violence, chance, and reason. Clausewitz emphasized the inherent uncertainty of war, the importance of moral forces (leadership, morale, public opinion), and the need for strategic thinking to adapt to specific circumstances. His framework saw war as a continuation of politics by other means—a rational tool that nonetheless operated in non-linear, unpredictable conditions.
Almost simultaneously, Jominian Strategic Theory offered a competing vision. Antoine-Henri Jomini, a Swiss-born officer who served in several armies, distilled war into a set of geometric principles centered on interior lines, concentration of force, and decisive battle. Jomini claimed that the correct application of these principles could guarantee victory. Where Clausewitz stressed friction and uncertainty, Jomini sought prescriptive rules. This contrast—between war as an art of political judgment and war as a science of linear deduction—became a recurring fault line in strategic history. Jomini's influence dominated military education in the nineteenth century, but Clausewitz's framework arguably proved more durable, surviving into the present as a living tradition rather than a historical curiosity.
Sea Power Theory, formulated by Alfred Thayer Mahan in The Influence of Sea Power upon History (1890), expanded the strategic domain beyond land warfare. Mahan argued that naval supremacy, sustained by a powerful battle fleet and overseas bases, was the key to national greatness. His framework differed from its predecessors by focusing on a different operational medium and, more importantly, by linking strategy directly to economic competition and imperial reach. Mahan did not reject Clausewitz or Jomini so much as extend strategic reasoning to a new environment, though his emphasis on decisive naval battle echoed Jominian thinking more than Clausewitzian ambiguity.
The First World War revealed the limitations of strategy confined to the battlefield. Grand Strategy Studies emerged in the interwar period to address this gap, most influentially in the writings of Basil Liddell Hart. Grand Strategy absorbed Clausewitz's political purpose but broadened the scope: it coordinated military means with diplomacy, economic pressure, industrial mobilization, and even propaganda. Where earlier frameworks treated strategy as the conduct of campaigns, Grand Strategy Studies insisted that policy must orchestrate all instruments of national power. The framework did not replace Clausewitz but incorporated and elevated his political logic, narrowing the space for purely operational thinking.
Airpower offered an even more radical expansion of the strategic horizon. Douhetian Airpower Theory, advanced by Giulio Douhet in The Command of the Air (1921), argued that air forces could bypass armies and navies to strike directly at civilian populations and industrial centers, thereby breaking an enemy's will to resist and winning wars quickly. Douhet's framework rejected the gradual attrition of trench warfare and challenged the primacy of the army—a departure from both Clausewitzian and Jominian assumptions about the centrality of land battle. Although Douhetian theory never achieved decisive validation in practice, it introduced the idea of strategic bombing and set the stage for nuclear strategy.
The atomic bomb shattered the foundations of classical strategy. Nuclear Strategic Studies emerged after 1945 to grapple with a weapon that could destroy entire societies. The framework broke sharply from earlier traditions: if a nuclear war could not be won on rational terms, then the purpose of strategy shifted from winning wars to preventing them. Nuclear strategists like Bernard Brodie, Thomas Schelling, and Albert Wohlstetter developed concepts of deterrence, mutually assured destruction, and crisis management—each premised on the idea that force could serve political ends only by not being used. This was a radical departure from Clausewitz, who assumed war was a rational political instrument, and from Douhet, who thought aerial bombardment could be decisive. Nuclear Strategic Studies narrowed the range of strategic behavior to signaling, bargaining, and the manipulation of risk.
At almost the same moment, a different kind of conflict demanded a different framework. Counterinsurgency Strategy grew out of the colonial wars and decolonization struggles of the 1950s. Thinkers such as David Galula and Robert Thompson argued that insurgencies could not be defeated by conventional military force alone; success required a combination of population security, political reform, economic development, and intelligence work. Counterinsurgency coexisted with Nuclear Strategic Studies without directly challenging it—the two addressed entirely different levels of conflict. Yet Counterinsurgency revived elements of Grand Strategy by insisting on the integration of military and non-military tools, and it implicitly questioned the nuclear obsession with deterrence by reminding strategists that most wars were fought inside states, not between superpowers.
By the 1970s, the limitations of rational-actor models in strategy became increasingly apparent. Strategic Culture Studies, first fully articulated by Jack Snyder in 1977 (in a RAND study on Soviet strategic culture), argued that a nation's strategic choices were shaped by deeply embedded historical experiences, national identity, and institutional traditions—not just by universal rationality. This framework challenged both the rationalist assumptions of Nuclear Strategic Studies and the universalism of Clausewitzian theory. Strategic Culture Studies contended that what counted as 'rational' was itself culturally constructed; the same situation could produce different strategies in different states. It did not replace existing frameworks but added a layer of explanation for persistent national differences.
In parallel, Political Economy of Strategy offered a rival challenge to rationalism—but from a materialist direction. Drawing on Marxist and institutionalist traditions, this framework argued that strategic choices were primarily determined by economic interests, resource constraints, and the dynamics of capitalist competition. Thinkers like Paul Kennedy (in The Rise and Fall of the Great Powers, 1987) showed how relative economic decline constrained strategic overreach. Political Economy of Strategy coexisted with Strategic Culture Studies in a state of productive tension: culture scholars emphasized ideational continuity, while political economists highlighted material incentives and structural imperatives. Both frameworks narrowed the explanatory reach of purely military analysis, though they disagreed on which factors were most fundamental.
The most recent major framework, the Practice Turn in Strategic Studies, emerged from broader developments in social theory. Drawing on Pierre Bourdieu's concept of practice, scholars such as Christian Bueger and Frank Gadinger argued that strategy is not a body of abstract theory applied to the world but a social practice produced and sustained through everyday organizational routines, embodied skills, and tacit knowledge. The Practice Turn questions whether strategy can be taught in classrooms or prescribed in manuals—a direct challenge to the Jominian tradition of codified principles and to the rationalist modeling of Nuclear Strategic Studies. It differs from Strategic Culture Studies by focusing less on national identity and more on the micro-level routines of military organizations. In this view, strategy is something actors do rather than something they have. The framework remains a minority position but has stimulated important debates about the relationship between theory and action in strategy.
Strategic history today is strikingly pluralistic. Clausewitzian Strategic Theory remains the most widely taught classic, valued for its insights into the nature of war and the role of political purpose. Grand Strategy Studies has flourished in the post-Cold War era, especially as scholars and policymakers grapple with rising powers and global challenges. Nuclear Strategic Studies endures as a vital subfield, though its assumptions are increasingly contested by those who argue for renewed attention to non-proliferation, arms control, and the risks of unintended escalation. Counterinsurgency Strategy saw a revival after 9/11 and remains influential among military professionals, even as its track record is debated. Strategic Culture Studies and Political Economy of Strategy continue to compete over how best to explain variation in strategic behavior; the former dominates area studies, the latter thrives in international relations and security studies. The Practice Turn is the newest entrant, gaining traction among scholars interested in the everyday work of strategizing.
Where these frameworks agree is in rejecting the notion that strategy can be reduced to a simple set of universal principles. All acknowledge that context matters—political, social, economic, cultural, technological. Where they disagree is on which context matters most and how it shapes outcomes. This disagreement is not a sign of weakness but of a healthy field wrestling with the complexity of using force in political life. The history of strategic thought is not a linear progression toward a final truth, but a series of debates that continue to unfold.
