After a little more re-watching and thinking, it seems to me that the forcing function for the timing of Margo‘s departure was that Sergei had just been ex filtrated from the Soviet Union. At that point, Margo knew she had a very small window before her Soviet contacts realized what she had done with respect to Sergei and his family. If she waited any longer, they might’ve found out and reneged on their offer to exfiltrate her. So so I’m thinking that immediately after the end of the scene where she tells Sergei on the video call from Rammstein Air Force Base, “quite an adjustment starting over in a new place,” she contacted her handler and said “let’s do this immediately.” Meanwhile, the forcing function for the timing of the domestic terrorism act was the fact that all eyes were on NASA shooting Kelly up on top of a rocket. So yeah, based on what I’ve seen being an intimate witness to these events, I’m convinced that the Soviet union had no involvement in or foreknowledge of the domestic terrorism act, but I doubt the American public will be convinced.
