Karl Liebknecht

Passive fatalism can never be the role of a revolutionary party, like the Social Democracy.

The failure of the Russian Socialist Republic will be the defeat of the proletariat of the whole world.

To the socialist no nation is free whose national existence is based upon the enslavement of another people, for to him colonial peoples, too, are peoples, and, as such, parts of the national state.

In the present imperialistic milieu there can be no wars of national self-defense.

Like a cyclone, imperialism spins across the globe; militarism crushes peoples and sucks their blood like a vampire.

Just as invasion is the true and tried weapon in the hands of capital against the class struggle, so on the other hand the fearless pursuit of the class struggle has always proven the most effective preventative of foreign invasions.

For capitalism, war and peace are business and nothing but business.

The Russian revolution was to an unprecedented degree the cause of the proletariat of the whole world becoming more revolutionary.
