Yeah. How events play out in Germany is almost irrelevant if we go by broad strokes.
If Moscow turns liberal, East Germany falls. If it doesn't, East Germany doesn't fall.
Though of course, the
specific events of 9.11.1989 are ridiculously easy to change. Just have Schabowski not be a complete, unprepared idiot - the guy who did a press conference so badly it ended his state
For context: The GDR government had initiated a new law that would allow travel to West Germany or West Berlin (technically not part of West Germany) without further restrictions. The idea was to then renounce the GDR citizenship of everyone who did that and not allow them back in - and thus get rid of the most pertinent troublemakers. However, Schabowski had been informed about this only just prior to the press conference, so he got a crucial detail wrong: He said that the new law about removing restrictions to travel would be effect immediate. Cue tens of thousands of people trying to cross to West Berlin the very same night, which eventually just overwhelmed the border guards. The people were then simply let through without any controls, without marking their passports, and so the government plans about kicking them all out were never put into effect. Instead, that was the very clear sign the GDR was over now.
Due to an accident. At a press conference.
Yeah, that's pretty easy to change. But chances are, the GDR will then simply fall in some other way I'm too unimaginative to think about right now.
