Strategic Theory

Carl von Clausewitz

1780–1831 · Strategic Theory


The Theorist of Friction

Clausewitz established something simple and profound: plans never survive contact with reality intact, and the ability to function in the gap between plan and execution is the actual strategic skill. His concept of friction — the accumulation of small obstacles that derail even the best-designed effort — applies to any complex undertaking. Strategy, for him, is never purely technical: it is always an extension of political will operating under irreducible uncertainty.
