This is the third of Mr. Dallin's books on Russia to appear in recent years. Unlike the two previous ones, which concerned Soviet foreign policy, the present volume presents the author's interpretations of the evolution of internal affairs under the Soviet régime. More than in his earlier works, Mr. Dallin, who has not been in Russia for many years, here displays a contentious and polemic rather than objective spirit. He does not like the Stalinist dictatorship, and the sooner it is over the better, he holds.
