Feels tacky to self-quote, but ... ... since we're discussing this anyway, I feel like I should elaborate. Yes, the Soviet Union is being portrayed in an antagonistic manner and the Russians are "the baddies", but it's done so in a way that completely aligns with my experiences. Regardless of the regime of the moment (so I also feel no need to differentiate between Soviet and Russian here), Russia is pretty consistently a fairly antagonistic place, both to foreigners and its own inhabitants. Even when you have interactions with fundamentally decent people, the paranoid and ruthlessly powerful state security apparatus, be it the Soviet KGB or the modern FSB, as well as the relentless brainwashing of the masses, poisons everything. The methods we've seen used are fairly true to real-world methods used by the KGB/FSB. So this really isn't "the Russians" being stand-in villains because you need villains. It's IMO a pretty informed portrayal of how a "partnership" with Russia might play out.
