I want to know the answer to the following question:
Who was skeptical of Stalin’s policies?
All the background I'm provided with is that "Some critics of Stalin's policy, such as the popular writer Viktor Suvorov, claim that Stalin's primary motive for signing the Soviet–German non-aggression treaty was his calculation that such a pact could result in a conflict between the capitalist countries of Western Europe.[citation needed]". Is that enough to answer the question?
Answer: yes
