Why can't Russia just win and take over the entire Ukraine? What's stopping them?

I thought according to /pol/, Russia was the most powerful and most military advanced country on earth?

their army hasn't recover after the Afghan war, but what's crazy is how the western allies did not defend Ukraine and stop the ziggers from the get go

I don't think I ever heard anyone on /pol/ say this. What a dumb strawman. The reason they can't take over Ukraine is because they're fighting the entirely of NATO. You already know this though, you silly little shill.
