Mao Zedong: War, this monster of mutual slaughter among men, will be finally eliminated by the progress of human society, and in the not too distant future too. But there is only one way to eliminate it and that is to oppose war with war, to oppose counterrevolutionary war with revolutionary war, to oppose national counter-revolutionary war with national revolutionary war, and to oppose counter-revolutionary class war with revolutionary class war.... When human society advances to the point where classes and states are eliminated, there will be no more wars, counter-revolutionary or revolutionary, unjust or just; that will be the era of perpetual peace for mankind. Our study of the laws of revolutionary war springs from the desire to eliminate all wars. Herein, lies the distinction between us Communists and all the exploiting classes. https://wordsmith.social/protestation/quotes#quote3366
