Reading that update made me think a German-Soviet Split is likely to happen, if Stalin takes over like OTL. Hitler may be a socialist and more pragmatic, but he's still Hitler and there's a trace of stubbornness and megalomania in him that won't stand simply taking orders from Moscow. Maybe from Lenin, the father of the Revolution, and maybe even for a while by Stalin as his successor, but eventually he's going to see something better for the German Communists and make a move. Not really the best mix with someone like Stalin who is the worst combination of paranoia and control-freakery for anyone working under him.
Then again, it took the Sino-Soviet Split seven years to start and ten to finish, so it may take a while.
Since we've jumped to 1923, I have to wonder about the wider European response. The French hitting harder won't win them any friends, but it seems like the Ruhr Uprising has taken a more revolutionary colour, and a socialist one at that. I can see a lot of Central and Eastern European states getting worried about how much the German government can control this. It's probably another reason that Moscow wants it to stop so that the other Communist Parties have room to breathe. I know the Left were sympathetic already, but that's likely increased.
As time goes on, however, I have to wonder if disarmament will be less popular among the Right. At some point, Hitler will take power, and I doubt that OTL's Appeasement would have anywhere close the number of advocates on the Right for a Communist Germany. During the 1920s, there'll probably be more calls for stronger ties with Mussolini's Italy from the Right ITTL, if the Red Menace grows stronger.
Rearmament in Britain may become a solid Right/Left question, if it's seen as being aimed at a Communist Germany. That's leaving aside what the likes of Poland, Austria, and Hungary do. The response from Europe could be more co-ordinated, but then again, they're also facing the Germans and the Soviets and nothing says solidarity like everyone else ganging up on you.
But first, we have to get there.
