Friends, Comrades, Brothers !
From under the blows of the world war, amidst the ruin which has been created by Tzarist Imperialist society - the Russian Proletariat erected its State - the Socialist Republic of Workers, Peasants and Soldiers. This was created in spite of an attitude of misconception, hatred and calumny. 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. The Russian revolution was to an unprecedented degree the cause of the proletariat of the whole world becoming more revolutionary. Bulgaria and Austria-Hungary are already in the throes of revolution ; revolution is awakening in Germany. But there are obstacles in the way of the victory of the German proletariat. The mass of the German people are with us, the power of the accused enemies of the working class has collapsed ; but they are nevertheless making all attempts to deceive the people, with a view of protracting the hour of the liberation of the German people.
The robbery and violence of German Imperialism in Russia, as well as the violent Brest-Litovsk peace and the Bucharest peace have consolidated and strengthened the Imperialists of the Allied countries ; - and this is the reason why the German Government are endeavouring to utilize the Allied attack upon Socialist Russia for the purpose of retaining power.
You have no doubt heard how Willhelm II, who, now that Tzarism has perished, is the representative of the basest form of reaction, - a few days ago made use of intervention in the affairs of proletarian Russia by the Allied Empires for the purpose of raising a new war agitation amongst the working masses ?
We must not permit our ignoble enemies to make use of any democratic means and institutions for their purpose; the proletariat of the Allied countries must allow no such thing to occur. We know that you have already raised your voice to protest against the machinations of your governments ; but the danger is growing ever greater and greater. A united front of world Imperialism against the proletariat is being realised, in the first instance, in the struggle aga inst the Russian Soviet Republic.
This is what I warn you against. The proletariat of the world must not allow the flame of the Socialist Revolution to be extinguished, or all its hopes and all its powers will perish. The failure of the Russian Socialist Republic will be the defeat of the proletariat of the whole world.
Friends, comrades, brothers arise against your rulers !
Long live the Russian workers, soldiers and peasants !
Long live the Revolution of the French, English, Italian and American proletariat !
Long live the liberation of the workers off all countries from the infernal chasm of war, exploitation and slavery!
