The invasion of Russia has given them at least small gains for the first time in a while but it really doesn’t change the overall situation as of right now. The territory gained is very small compared to what they’ve lost.

Russia would have just continue letting them gain more and more territory until they have enough for some kind of exchange, but that seems unlikely. They were caught off guard, but now that they’re defending, further advances will become difficult and it’s likely to soon reach another stalemate like the other fronts.
