"PROVEN destruction of the Nordstream pipeline"

Please provide a link to this proof, please.

I cannot find any official statement by any government or agency declaring positively that the Russians blew up their own pipeline.

The official NATO statement does not assign blame.

The official Swedish enquiry concluded that it had been an act of sabotage but could not determine who was to blame.

The USA has also refused to assign blame, and Secretary Blinken would only ay that the sabotage of Nordstream, for the US, "offers tremendous strategic opportunity for the years to come".

I can only assume that if the Russians had done it, then neither NATO, nor the US, nor Sweden would be "shy" about assigning the blame where it belonged.
