"History has prepared our party for various tasks. However defective our state machinery or our economic activity may be, still the whole past of the party has psychologically prepared it for the work of creating a new order of economy and a new state apparatus. History has even prepared us for diplomacy. It is scarcely necessary to mention that world politics have always occupied the minds of Marxists. But it was the endless negotiations with the Mensheviki that perfected our diplomatic technique; and it was during these old struggles that Comrade Chicherin learned to draw up diplomatic notes. We are just beginning to learn the miracle of economics. Our state machinery creaks and groans. In one thing, however, we have been eminently successful – in our Red Army. Its creator, its central will, is Comrade L.D. Trotsky."
