Strategic Theory — Canonical Survey

BLUF

Strategic theory is the systematic effort to extract generalisable principles from the study of war and statecraft that can guide future decision-makers. The Western canonical lineage spans from pre-modern military manuals through Enlightenment military rationalism, the Napoleonic rupture, Clausewitz’s philosophical synthesis, Mahan’s sea-power school, and the 20th-century divergence into nuclear deterrence theory and indirect-approach doctrine. The Eastern lineage — Sun Tzu and later Chinese strategic thought — runs parallel and is increasingly operationally relevant as the PRC’s doctrinal framework draws on both traditions. This survey maps Stage 0 through Stage 5 of the canonical arc to provide the structural context within which modern hybrid-threat and cognitive-warfare doctrine should be situated.

Stage 0 — Cabinet War and the Military Enlightenment (pre-1789)

The European jus publicum Europaeum produced a system of structurally limited war governed by dynastic interest, balance-of-power logic, magazine-dependent logistics, and Vauban siegecraft. The theoretical project of the Military Enlightenment was to reduce war to a science — discoverable principles capable of producing victory predictably. Principal theorists:

  • Sébastien de Vauban — codified siegecraft as predictable engineering
  • Maurice de Saxe — discipline as “the soul of armies”
  • Frederick the Great — aggressive offensive doctrine within resource constraints; first to break with purely defensive-minded war in the era
  • Henry Lloyd — interior lines; integration of moral and socio-economic factors
  • Jacques-Antoine-Hippolyte de Guibert — prophetic bridge figure: foresaw the “nation in arms” that would sweep away Cabinet War; linked military effectiveness to political-social structure

The intellectual pathology: the search for a rational key to war — a fundamental mistake Clausewitz would spend On War refuting. See Cabinet-War-Paradigm for the full analysis of the Westphalian military order.

Stage 1 — Jomini and the Scientific School

Antoine-Henri Jomini (Summary of the Art of War, 1838) attempted to fulfill the Military Enlightenment project in the aftermath of the Napoleonic Wars: distil from Napoleon’s campaigns a set of prescriptive geometric principles (interior lines, concentration at the decisive point, strategic lines of communication) capable of systematic application.

Jomini’s influence has been enormous and, many argue, pernicious: his emphasis on geometric clarity and rational planning became the dominant framework for 19th-century military education and partially shaped US Army doctrine well into the 20th century. The JOPP (Joint Operational Planning Process) retains Jominian DNA.

Clausewitz’s critique (implicit): Jomini’s system is elegant precisely because it abstracts war from its most important feature — political purpose and the friction of human will. A system that works on paper breaks down against a thinking adversary. The JADC2 / Mission Command paradox in contemporary doctrine (see Strategic-Coherence-21st-Century) is the living heir to the Jomini-Clausewitz debate.

Stage 2 — Clausewitz and the Philosophical School

Carl von Clausewitz (Vom Kriege / On War, published posthumously 1832) is the unavoidable foundation of Western strategic theory. Three contributions dominate:

The Trinity

War is governed by a dynamic non-linear interplay of three tendencies:

  • Passion (primordial violence, hatred, enmity) — primarily the domain of the people
  • Chance (probability, friction, uncertainty) — primarily the domain of the military commander
  • Reason (war’s subordination to political purpose) — primarily the domain of the government

The correct reading is dynamic tendencies, not a static social-actor checklist. A Passion-dominated Trinity (Nazi Germany) produces predictable strategic overreach; a Reason-dominated Trinity without Passion produces armies that cannot sustain a war’s demands. Analysing imbalances within an adversary’s Trinity is a predictive diagnostic tool.

Friction and Fog

War is characterised by friction — the difference between war on paper and war in reality — and fog — the irreducible uncertainty of operations. No plan survives first contact. The commander’s art is managing friction, not eliminating it (contra Jomini and contra JADC2). Assessment: JADC2’s promise of a frictionless “God’s-eye view” is the most significant contemporary repeat of the Jominian error.

War as Continuation of Policy

The most mis-cited sentence in strategic theory: “War is merely the continuation of policy by other means.” The critical clause is by other means — war adds its own grammar (violence, friction, chance) to political language. When war’s grammar overwhelms its political logic, Clausewitz’s worst-case emerges: war gravitating toward its absolute form — pure violence without political constraint. See the Partisan-Theory-Schmitt analysis of how Schmitt diagnosed the breakdown of the justus hostis framework that preserved Clausewitzian limits.

Stage 3 — Mahan and Sea Power

Alfred Thayer Mahan (The Influence of Sea Power upon History, 1890) transposed Jominian principles onto maritime strategy: national greatness derives from command of the sea, achieved through a decisive-battle navy, merchant marine, and global basing network. Mahan’s “five strategic keys” (Dover, Gibraltar, Suez, Malacca, Cape) remain structurally accurate as chokepoint analysis.

Mahanian legacy: US naval expansion (Puerto Rico, Guam, Philippines) was executed as Mahanian chokepoint acquisition; the contemporary INDOPACOM posture is the same logic modernised. The Economic Chokepoints — Coercive Statecraft analysis is structurally Mahanian. See also Power Projection for the contemporary expression of command-of-the-sea doctrine.

Stage 4 — Sun Tzu and the Eastern School

Sun Tzu (The Art of War, c. 5th century BCE) represents a fundamentally different strategic epistemology:

  • Supreme excellence is subduing the enemy without fighting — through deception, information advantage, and psychological dislocation
  • Shih (strategic advantage, positional power) — manoeuvre and pre-positioning to make the fight unnecessary
  • Deception as a primary strategic tool, not an adjunct to kinetic operations

The PRC’s Three Warfares doctrine (public opinion, psychological, legal warfare) and the concept of “intelligentized warfare” (zhinenghua zhanzheng) targeting “mind superiority” (zhinaoquan) are direct doctrinal heirs of the Sun Tzu tradition, synthesised with Leninist political-warfare theory and Maoist “people’s war” doctrine.

Contemporary relevance: the transparent battlefield (see Strategic-Coherence-21st-Century) elevates Sun Tzu’s cognitive approach from historical alternative to strategic necessity — when physical concealment is impossible, cognitive opacity becomes the decisive asset.

Stage 5 — 20th-Century Divergence

Liddell Hart and the Indirect Approach

B. H. Liddell Hart (Strategy, 1954) systematised the indirect approach: dislocation before destruction — physical or psychological unmooring of the adversary before kinetic engagement. Liddell Hart drew on Scipio Africanus, Sherman’s March, and British Great War experience to argue that the direct Clausewitzian approach (attrition toward decisive battle) was obsolete. Relevance: MDO’s cognitive-collapse objective is a Liddell Hart descendant.

Nuclear Deterrence Theory

The Manhattan Project and Cold War produced an entirely new theoretical domain: deterrence theory (Brodie, Schelling). The key departure from classical theory: the goal shifts from winning to preventing the adversary from acting. Mutually assured destruction, the stability-instability paradox, and the role of risk and commitment in coercion all become foundational. Contemporary nuclear-coercion as a Russian strategic tool (see Revisionist-Powers) is deterrence theory deployed offensively.

Fourth-Generation Warfare / Hybrid Warfare

Late-20th and 21st-century theoretical developments (Lind’s 4GW, Hoffman’s hybrid warfare, Gerasimov Doctrine debates) represent the return of Clausewitzian insight that war’s political and social dimensions cannot be bracketed: irregular adversaries, non-state actors, and revisionist states all exploit the seams between conventional doctrine categories. See Hybrid Threats and Hybrid Warfare for the contemporary synthesis.

The Schmittian and Post-Structural Strands

Carl Schmitt’s Theorie des Partisanen (1963) introduced the political-philosophical analysis of irregular warfare — the Partisan as the figure who inhabits the legal vacuum when the Westphalian justus hostis framework breaks down. Deleuze-Guattari’s War Machine, Agamben’s homo sacer, and Baudrillard’s simulacrum extend this into the terrain of identity, biopolitics, and information. See Partisan-Theory-Schmitt for the full canonical treatment of this strand.
