We suggest you turn to the Tao Teh Ching:
31. MAINTAINING PEACE Weapons of war are instruments of fear, and are abhorred by those who follow the Tao. The leader who follows the natural way does not abide them. The warrior king leans to his right, from whence there comes his generals' advice, but the peaceful king looks to his left, where sits his counsellor of peace. When he looks to his left, it is a time of peace, and when to the right, a time for sorrow. Weapons of war are instruments of fear, and are not favoured by the wise, who use them only when there is no choice, for peace and stillness are dear to their hearts, and victory causes them no rejoicing. To rejoice in victory is to delight in killing; to delight in killing is to have no self-being. The conduct of war is that of a funeral; when people are killed, it is a time of mourning. This is why even victorious battle should be observed without rejoicing. -- tr. S. Rosenthal
