Chamberlin is never easy reading, but he is important. He is one of the more maturely seasoned correspondents, objective in his appraisal of Russia, yesterday and today and tomorrow. He guards his statements pro-Soviet Russia with BUTS -- which makes one feel that he errs on the side of conservatism, but in the final analysis, his is a useful middle-of-the-road view. Historically, this is one of the best reassessments of the Russian Revolution, in all its phases, that has been published. More important, perhaps, is his analysis of the changes in Russian policy, from Lenin to Stalin; the factors responsible for the withstanding of the Nazi onslaught; the growth of nationalism, the natural features strengthening the industrial and economic development, the lessening of interest in world revolution -- all factors that indicate that Russia, as well as America, has a stake in post-war world peace.
