Capitalism is war; socialism is peace.
Karl Liebknecht
For capitalism, war and peace are business and nothing but business.
Like a cyclone, imperialism spins across the globe; militarism crushes peoples and sucks their blood like a vampire.
The aim of my life is the overthrow of monarchy.
Long live the liberation of the workers off all countries from the infernal chasm of war, exploitation and slavery!
Imperialism is not the creation of any one or any one group of states.
The basic law of capitalism is you or I, not both you and I.
In capitalist history, invasion and class struggle are not opposites, as the official legend would have us believe, but one is the means and the expression of the other.
Workers, comrades, and you, women of the people, let not this festival of May, the second during the war, pass without protest against the Imperialist Slaughter.
In the present imperialistic milieu there can be no wars of national self-defense.
The new Germany has the unquestionable right to hold its tongue between its teeth.
The Russian revolution was to an unprecedented degree the cause of the proletariat of the whole world becoming more revolutionary.
Consider well this fact: As long as the German people does not arise and use force directed by its own will, the assassination of the people will continue.
Passive fatalism can never be the role of a revolutionary party, like the Social Democracy.
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.
But Socialism, alone, can bring self-determination of their peoples.
Class struggle: external peace, international solidarity, peace among peoples. This is the sacred slogan of international socialist democracy that liberates nations.
Incendiary capitalism is carrying its out evil works more dangerously than ever, and is doing so in the increasingly dangerous neighborhood of the powder kegs that are the great European military powers.
International socialism recognizes the right of free independent nations, with equal rights.
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.
The failure of the Russian Socialist Republic will be the defeat of the proletariat of the whole world.
This republic represents the greatest basis for that universal socialist order, the creation of which is at the present time the historic task of the International Proletariat.
Through this experience we have been warned - learn everything, don't forget anything!
Yes, Socialists should defend their country in great historical crises.
