The only entity that clearly benefits from this is the US. It ensures Europe can't give in no matter how cold it gets this winter and it hurts Russia financially. Ukraine of course is hurt no matter what. Doesn't mean the US did it, but if you look at a map and try to figure out how the Russians would have gotten there undetected and did the damage and slipped out undetected again, well it's just not credible. And Europe certainly wouldn't put themselves in an even more precarious position that they already are. So Occam's Razor applies.
