"Therefore, now that we have won power, our duty is to consolidate the dictatorship of the proletariat with all the available forces, to perfect the instruments of revolutionary violence, to improve vigilance, and to always be prepared to rebuff enemy attempts to sow trouble and start a counter-offensive. Only in this way can we ensure the further peaceful development of the revolution."
