Stalin's time horizon for war with the other great powers is an important factor. He gladly used force against small states but how early would he be willing to invade another great power? There are reasons to believe he followed a "turtling" strategy like the Western powers, stalling his rivals to gradually build up his strength. But if Suvorov was right then he was willing to attack early, and a peaceful Germany would be at a serious risk.
On the other hand an early attack against a peaceful Germany could trigger immediate action from the West.
