meh those little conflicts are barely relevant. however not only did the soviets attempt an actual invasion of europe after ww1, after failing they then proceeded to overtly fund and incite uprisings and takeovers in several nations, including germany. they weren't subtle either, they stated their intentions of establishing the comintern (world wide communism) and acted on it. and apparently britain and france didn't care, which shows their complicity. these were acts of war, not much diff to what America does today in many places, except it was x10 what America does, they were far more aggressive. when the soviets had their agents in poland massacring ex-germans and even making some forays into german territory, that was the start of ww2. germany reacted, they formed a pact neither intended to honour, but one germany needed and the soviets used as bait, because it presented the false possibility that britain and france wouldn't declare war if the soviets weren't on board and they also had taken half of poland. this hope is proven by the fact that the germans had no western forces for the first few weeks of the war. the war of nazi germany vs the soviets was always going to happen however, and the soviets were always trying to play for time to build up their forces.. and for good reason, because germany would've steamrolled them 1 on 1. it was never germany trying to conquer europe, they were defending the old order of europe from those who were trying to conquer europe with a 'new order'.
