Sun Tzu — "The general who has no skill in strategy will be defeated."

"The greatest victory is that which requires no battle."

"The opportunity of defeating the enemy is provided by the enemy himself."

"Know your enemy and know yourself and you can fight a hundred battles without disaster."

"Thus it is that in war the victorious strategist only seeks battle after the victory has been won, whereas he who is destined to defeat first fights and thereafter looks for victory."

"Therefore, the skillful leader subdues the enemy's troops without any fighting; he captures their cities without laying siege to them; he overthrows their kingdom without long years of campaigning."
