For me the fact that America hasn't accused Russia of being behind it is very telling. If it was,, they would be using every opportunity to accuse Russia of doing so, and Denmark or Sweden would use it to trigger Article 5. In other words, if you think Russia is behind it, you accept that the NATO defensive treaty is a bluff.It looks like the pipelines could be done for.
Also. I wouldn’t eat any fish that comes from the Baltic Sea for a while.
If it is the UK or US behind the explosion, there is no way they will get away with it. Sooner or later the truth will come out. Russia and Germany will be able to sue them to get back the costs of the pipeline.
From the Russian point of view having the pipe blown up is fine. They should have cut off gas to Europe already.. Cheap energy for Europe is now a thing of the past, they will forever be indebted to the Middle East for oil and gas. That in turn will mean that Israeli colonial project is as good as finished.
