Russia appeared to be the weakest link in the enemy chain. The task therefore was gradually to loosen it, and, when possible, to remove it. This was the purpose of the subversive activity we caused to be carried out in Russia behind the front--in the first place promotion of separatist tendencies and support of the Bolsheviks. It was not until the Bolsheviks had received from us a steady flow of funds through various channels and under different labels that they were in a position to be able to build up their main organ, Pravda, to conduct energetic propaganda and appreciably to extend the originally narrow basis of their party. The Bolsheviks have now come to power; how long they will retain power cannot be yet foreseen. They need peace in order to strengthen their own position; on the other hand it is entirely in our interest that we should exploit the period while they are in power, which may be a short one, in order to attain firstly an armistice and then, if possible, peace.
