I know its a joke but just to note: I'd love to see Germany "march through Poland" given the poor state of Germany's armed forces. As it is rn, Poland alone could most likely reach Russia's heart in a couple of weeks of conventional warfare and debilitate Russian critical infrastructure long before that. Barring nukes of course, which is basically all the Kremlin would have to hang on to in a full out direct confrontation given just how incompetent their armed forces have proven to be.
