Hello,
I've done a spanish game yesterday as republicans, and I had the same problem: The russians sent me 5 mountaineers divisions, which just stood idle, letting me doing all the job. Actually they finally decided to react, but I was already winning, they just helped me to reduce a stack of enemy units I had already encircled, so that was not the most difficult part. On the other side, the italian and german divisions were actually active!

The good news is that it's still possible to win, as I managed to do it.
If you need some advice to optimize your strategy, i've asked this a few days before (that was before the patch comes out, but things didn't change much on this point), it was on this thread:

Those were good advice, thanks again to those who helped me
