“… we see that the real victims of this war are representatives of the working class of Ukraine and Russia…For us, the war is terrible not because governments and borders change, but because people die.”

“…As social-revolutionary proletarians, communists, anarchists, we have absolutely no material interest in siding in any way with the capitalist State and its democracy, whatever it looks like, with our class enemies, with our exploiters…We can therefore only salute the proletarians who refuse to position themselves in one or the other of the bourgeois camps…Greetings then to all of you who refuse to sacrifice yourselves on the altar of war, misery and homeland!!!
And the day, which we hope is very close, when the proletarians will take to the streets of Moscow and Kiev, and of all the big urban areas of Russia and Ukraine, chanting with one voice “Putin and Zelenski, get out!”…”
