It is possible to suspect that Tsarist Russia was a wrong starting point for an experiment in revolutionary communism, but I think rather the problem was in the fast pace of the period, and the distortion of judgment due to the first world war. But a more capable map of the path to communism could have helped. Marx/Engels, for good stated reasons, refused to map out the path to a postcapitalist system. But in retrospect that was perhaps a mistake: people in a confusing situation, created not least by Tsarism and the first world war, made decisions that were both ad hoc and binding in the emergent creation of a communist experiment. What is to be aimed at should be specific so that the passage to an aborted version can be seen in advance.
