Is even possible to defeat the Intermarium?

I had a go at Sweden yesterday trying to restore the old order and what-not. First mission was to try and save the Russian Empire, so I went in on Finland with meta 27 divisions.

My progress on Finland was slow cause of supply, but it wouldn't have mattered if Russia hadn't collapsed immediately. They stand absolutely no chance against the Intermarium; I looked at their buffs and they're insane. Massive attack and defence buffs generally, equally huge buffs for core territory etc.

I just think it's kind of nuts. Like what's the point of playing any of the Russian tags when you just get attacked by this overpowered faction a few months later?? It doesn't help that Russia still has its recovery debuffs as well.

TLDR: Intermarium too overpowered and makes any Russia kind of pointless to play as.
