Howdy!

This question will be hard to answer because at its very nature it is speculation.

We do know that the Soviet Union feared a war with Nazi Germany. Ideologically the two were polar opposites and conflict would surely arise. They both fought previously as proxies in the Spanish Civil War. However, an argument could be made that even the Soviet Union and the USA had strong ideological differences and it led to proxy wars, but never outright conflict between the two nations.

Lets delve now into some academic work though. There has been arguments made by some historians that the Soviet Union was planning to attack the Germans in the Summer of 1941. The main proponent of this is Viktor Suvorov in his book Icebreaker. The book has a myriad of problems. The gist is that basically the Red Army had more of an "offensive" capability at the time and it cost the Red Army a huge swath of losses when they got preemptively attacked by the Germans.

David Glantz, who is a great academic on the Eastern Front disagrees with this assessment. He argues that the Red Army was woefully underprepared for any invasion whatsoever. The Red Army was barely prepared for a defensive war. Concluding with "Stalin may well have been an unscrupulous tyrant, but he was not a lunatic." (Stumbling Colossus).

Conjecture: I mean, it isn't out the realm of possibility. However, majority of historians disagree that the Soviet Union was going to preemptively attack Nazi Germany in 1941. Beyond that would be purely speculation.
