Oh, NS2 sabotage is quite relevant as it shows that "someone" can blow up (partially) German infrastructure while Germany have no guts to even wink in the direction of the perpetrator. Not exactly a definition of a sovereign country.
NS2 was not quite German infrastructure, it's really Russian infrastructure. It was also entirely irrelevant for Germany at that point, no gas ever has flown through it and none would have almost certainly even if it were still fully intact (one strand is undamaged).
We don't know if the German government knows who did this. So I don't think we can draw any conclusions from the lack of action here, we simply do not have enough information.
>NS2 was not quite German infrastructure, it's really Russian infrastructure
What are you talking about? Western companies literally own half of NS2.
>no gas ever has flown through it and none would have almost certainly even if it were still fully intact (one strand is undamaged)
I wonder if intentionally delayed certification of the pipeline by Germany has anything to do with "no gas ever has flown". The point is: NS1 + NS2 was a constant temptation for Germany and blowing it has removed the "wrong" incentive.
Basocally everyone wanted NS2 to be gone, including the Russians. So in all honesty, I'd expect saboteurs frok NATO country A helping out saboteurs from non-NATO country B with explosives and detonators if needed.
By the way, nobody wanted NS2 by the time it was technologocally ready. Funny enough, if Trump wouldn't have been president a deal for CNG anf LNG would have been had a lot easier and earlier.
>Basocally everyone wanted NS2 to be gone, including the Russians
I call BS. Not only have they invested a significant amount of money into it, they also sell gas to Europe through Ukraine even today. I think they would like to have working pipelines which do not cross any intermediate states, even in offline state.
