As Andrew said, there is no worry here at all because you build in Berlin before the US and UK can go, US has no ground units so all it can do is sacrifice planes, and UK can only bring a three tanks and two infantry as ground forces as an assault force.
Depending on what those gray and black ships are in sea zone 112, you might even have an opportunity to destroy the Allied Atlantic fleet.
I would build 8 infantry, a fighter, and a destroyer in Germany.
Use your Germany tanks and tactical bomber to kill the UK tank in Yugoslavia (being sure the tactical bomber makes it back to Germany), and use a single infantry to recapture West Germany because you do not want the US building there.
Place the destroyer in sea zone 113, forcing the US to clear the zone for the UK (and preventing the US from sacrificing its planes in Germany to make a UK victory more likely) or forcing the UK to clear sea zone 113 (preventing any amphibious support shots) (depending on what those black and gray ships are!).
Consider building three fighters at the Novgorod IC – those fighters can threaten sea zone 112, along with the fighter and tactical bomber from Germany. Retreat at least one infantry from Finland to cover the fighters.
I don’t think you need to move anything back from Moscow – I think you need to go get your next two NOs in Caucasus and Volgrograd. I would consider building a strat bomber in Moscow to help with the threat to the Allied Atlantic fleet.
EDIT: Well, I missed that it’s currently the US turn from the original posting. If this is the case, if the US sacrifices its planes and gets lucky with the bombard, you might lose the battle but the odds are still heavily on your side (assuming green chips are three units).
