Roberts has come under criticism from Andrew Bacevich, who claims in a review in The National Interest that Roberts is overly sympathetic towards Stalin, taking the word of the Soviet leadership uncritically in his writings, thus presenting a biased view and significantly undermining the usefulness of his scholarship. According to Jonathan Haslam, Roberts relies too heavily on edited Soviet archival documents and goes too far in his conclusions, therefore making his accounts somewhat one sided and by no means telling a full story.
In an interview with George Mason University's History News Network, following the publication of Stalin's General: The Life of Georgy Zhukov, Professor Roberts said:
"The Soviet Union was responsible for some of the most epic achievements and most gross misdeeds of our age... I have no difficulty in joining the condemnation of the Soviet system's violence, terror and repression. But if you believe force and oppression were the only factors driving the Soviet Union then you will never understand why the USSR lasted so long and achieved so much, not least the victory over Hitler. If we don't acknowledge the roles of ideology and aspiration in creating political systems we will be ill-prepared to face the challenges of dynamic and powerful authoritarian politics in the future."
