I saw this a while ago and I'll try to paraphrase it, but I probably won't get it exactly right. In the pre-Russian revolution era the Russians had pretty extensive correspondences with western European communists, and they had major disagreements about the course of revolution. The western Marxists wanted the Russians to not have a revolution, as they believed that following Marxist historiography a revolution needed to happen in an industrial core, not in an extractive/agrarian economy. The business of industrializing an economy will always be ugly, and they feared a Revolutionary Russian state rushing this process would poison the well of communism with the misery that would create. Better to let the capitalists take the blame for the suffering of industrialization and then have the communists come in, seize the MOP and reap the rewards.

Of course, the Leninists didn't listen, did their revolution, and went through the fairly unpleasant process of industrializing, but in the end were successful and were able to beat the industrialized Germans. China had a fairly similar process with a revolution happening within an agrarian, extractive, and extremely poor economy, and they've also had to deal with mechanizing their economy, which took a different path, but again has been pretty successful.

It would be nice if the communists had gone and won a revolution in France or Germany or England in the late 19th or early 20th centuries, but so far communists have only had success in the colonized world and not in the industrialized metropole. And that means that communists have had to do the ugly work of industrialization, and suffer the blame of that process.
