Lots of moments of people looking into the camera and going "how could communism do this?" which is cringe, but otherwise it's a fantastic story of human drama and how bad shit can get. Funny, I read this morning that Gorby is now dead, weird timing.

seriously, major spoiler
There's a shot at the very end of the S3 finale which shows Margo step out on a balcony in Moscow, so I'm pretty sure we're getting something in that direction for S4 (though she could well become some kind of double agent, not fully committing to her defection or sth; we'll have to wait)

Yeah, I guess you're right about that. I didn't really class that as a positive defection in my head since the storyline is that she was blackmailed by the ebil authoritarian commulists into handing over US space tech (which is even more :brainworms: since Russian space propulsion tech was always ahead of ours) and she's implied to have just run away and let the bombing seem like her death.
The constant "RUSHA FLYING 100% COPY OF AMERICAN THING" really gets my goat so much
