Yes but I think this will change the psychology of the allies in a positive direction for the defense of Ukraine.
Another point about who did it that not many people are talking about.
The Inside Russia youtube channel is run by a self exiled Russian expert on energy, dams, etc.
He points out that even if the Russians didn't blow it up, simple NEGLECT of maintenance of the dam is virtually the same thing.
The dam was on Russian occupied land, they took over running the dam, they are responsible for neglect if that caused the tragedy.
But I still think they exploded it.
