What is essential in war is victory, not prolonged operations.

This maxim is attributed to Sun Tzu’s treatise *The Art of War*, in the section commonly translated as “Waging War” (Chapter 2). In that chapter, Sun Tzu argues that war rapidly drains a state’s resources: armies consume supplies, equipment wears out, and prolonged campaigns sap morale and invite opportunism from rivals. The line appears as part of his broader warning that even tactically capable forces can be strategically ruined by delay. The historical backdrop is the Warring States milieu, where competing polities faced constant pressure to win quickly or risk economic exhaustion and political instability at home.

The quote frames victory—not the mere continuation of fighting—as the true strategic objective. Sun Tzu is not praising aggression for its own sake; he is emphasizing economy of force and the political nature of war. A campaign that drags on may still “fight well” in a narrow sense, but it can destroy the very ends it is meant to secure by consuming wealth, weakening governance, and hardening resistance. The aphorism thus favors decisive strategy: clear aims, rapid concentration of advantage, and methods (including deception, diplomacy, and disruption of enemy plans) that shorten conflict rather than glorify endurance.
