The victory of the Germans over Russia was the pre-condition for the revolution, which was the pre-condition for Lenin, who was the pre-condition for Brest! The same applies in the west! First victory in the west and collapse of the Entente, then we shall make conditions which they have to accept! And they will be framed purely in accordance with our interests.
