《战国策·齐五·苏秦说齐闵王》
臣听说战争取得大捷，士卒伤亡惨重，百姓因防务而疲惫不堪，城郭也会损毁得面目全非。兵死于战，民疲于内，城郭破败，国君是不会高兴的。
不啬于战攻之患也。由此观之，战攻之败，可见于前事。
I have heard that when a war is won with great success, many soldiers are killed and wounded, and the people are exhausted from defending themselves, and the city walls are damaged beyond recognition. When soldiers die in battle, the people are exhausted at home, and the city walls are destroyed, the sovereign will not be happy.
