Sun Tzu's military thinking focuses on achieving victory through different strategies: 'first victory' prepares for war, 'complete victory' aims for minimal losses, and 'fighting victory' forces the enemy to surrender. 'First victory' sets the stage for 'complete victory' and 'fighting victory'. If 'complete victory' fails, 'fighting victory' steps in. Sun Tzu's ideas on victory are still relevant today for national and military strategies.
