But eventually, the findings will be published.
Nope. In fact, Germany already promised not to reveal it.
US/GB blew it up, period.
Germany hasn't said they have any conclusion yet. And the Swedish investigation might very well have the same conclusion. But that doesn't mean Russia didn't do it. Or that Americans did it.
The prime suspect is Russia, but US and GB are way down in the list. The Americans can't keep anything a secret for long, and they know it, so it would be idiotic for Biden to risk ruining relations to its European allies over a pipeline that wasn't being used anyway. UK has its own internal problems and couldn't be bothered, and they don't have much stake in LNG business anyway. If it was someone other than Russia, Ukraine is probably the second most likely suspect.
You really think that Russia would do it? what for?
Blow their bridge too? Really?
No, I don't think Russia blew up their own bridge. Because it's important for logistics, and was Putin's pet project.
The Nordstream pipes were not currently delivering any gas, and that was by Russia's choice, not Germany's. And it looks very likely that they won't be for many years. Putin sabotaging them is just finding a new use for useless infrastructure: a distraction, propaganda, warning that sudden explosions might happen to Norwegian pipeline or communication cables,
force majeure for not delivering gas, excuse for military presence in the Baltic... who knows what that madman has in mind.
