To destroy governmental violence only one thing is needed: it is that people should understand that the feeling of patriotism which alone supports that instrument of violence is a rude, harmful, disgraceful, and bad feeling, and above all immoral. It is a rude feeling because it is natural only to people standing on the lowest level of morality and expecting from other nations such outrages as they themselves are ready to inflict. It is a harmful feeling because it disturbs advantageous and joyous peaceful relations with other peoples, and above all produces that governmental organization under which power may fall and does fall into the hands of the worst men. It is a disgraceful feeling because it turns man not merely into a slave but into a fighting cock, a bull, or a gladiator, who wastes his strength and his life for objects which are not his own but his government’s. It is an immoral feeling because, instead of confessing himself a son of God (as Christianity teaches us) or even a free man guided by his own reason, each man under the influence of patriotism confesses himself the son of his fatherland and the slave of his government, and commits actions contrary to his reason and conscience.
–Leo Tolstoy, “Patriotism and Government,” in Selected Essays
