“ | Socialists have always condemned war between nations as barbarous and brutal. But our attitude towards war is fundamentally different from that of the bourgeois pacifists (supporters and advocates of peace) and of the Anarchists. We differ froth the former in that we understand the inevitable connection between wars and the class struggle within the country; we understand that war cannot be abolished unless classes are abolished and Socialism is created; and we also differ in that we fully regard civil wars, i.e., wars waged by the oppressed class against the oppressing class, slaves against slave-owners, serfs against land-owners, and wage-workers against the bourgeoisie, as legitimate, progressive and necessary. We Marxists differ from both the pacifists and the Anarchists in that we deem it necessary historically (from the standpoint of Marx’s dialectical materialism) to study each war separately. In history there have been numerous wars which, in spite of all the horrors, atrocities, distress and suffering that inevitably accompany alt wars, were progressive, i.e., benefited the development of mankind by helping to destroy the exceptionally harmful and reactionary institutions (for example, autocracy or serfdom), the most barbarous despotisms in Europe (Turkish and Russian). Therefore, it is necessary to examine the historically specific features of precisely the present war. | ” |
