Your citation there shows von Braun being a total shitstain, but not necessarily a racist shitstain. He lacked morals and principles, and used slave labour; but it doesn’t seem like he cared much about who the slaves were. So he doesn’t seem to have ended up having any qualms about hiring black people. I suppose it makes him slightly more progressive, but not necessarily any less of a bad person.
Regarding Shpakovskii, it’s unclear what he was accused or convicted of, and it’s unclear if whatever the allegations were were also true. But given the example provided, it seems the worst thing he could be getting accused of there is stealing from partisans/Jewish people, which is bad but not a war crime (assuming his case is indeed ‘similar’ to the example provided in that text).
I’m not sure we can figure out what this guy did exactly with just online sources, I can’t exactly find much more on the man. Given the evidence, he could in theory have been a Chetnik, which would fit his motivations and background. Being a full-blown Nazi seems less likely. That doesn’t mean he wasn’t involved in any war crimes, but there’s currently nothing that suggests that he was.
Maybe look a little bit harder. In the 1990s the Baltics each saw a majority vote for pro-independence parties. Each of the three states organised a referendum on independence, and all three voted in favour (by 77%, 78% and even 90+% in Lithuania).
The march 14th 1991 referendum you’re probably referring to was not held in the Baltics. Additionally, it is often framed as a vote against independence, but that’s not really what was on the ballot in the first place. The referendum was on the New Union Treaty, and was phrased as:
Emphasis mine. Note that the alternative in this case was the USSR continuing as it existed before, meaning there was no vote on the dissolution of the union. The majority voted in the direction of more sovereignty for the constituent states, the closest thing to independence on the ballot.
Pro-Soviet groups in the Baltics did attempt to hold their own independence referendums, but none managed to reach a 50% turnout and they were boycotted by the Baltic Supreme councils.
