How do you fit in all the other facts, some already mentioned here in the comments, and many many more on

https://en.wikipedia.org/wiki/2022_Nord_Stream_pipeline_sabotage

I'll highlight a few I find remarkable.

- Candidate Nato-member, Sweden's Foreign Minister Ann Linde, was suspiciously quick in stating that "The suspected sabotage against the Nord Stream gas pipelines does not constitute an attack on Sweden".

This means she knows who did it and considers them "friendlies". This rather disqualifies Russia does it not?

- Also Daniel Stenling, Sweden’s top counterintelligence official, declined to speculate on a perpetrator.

- Swedish government's decision to keep details of its inquiry secret from Western allies has prompted whispered speculation that perhaps investigators have cracked the case and are strategically keeping quiet.

- The Western media is suspiciously silent on the topic. If it had been Russia we would have seen an orchestrated 24/7 media-feeding frenzy. A bit of spin, some timid trying to frame it on Russia, but not too much as they know if proof were to come and catch them blatantly out, it would badly arm their already well-bruised reputation for truth-telling.

- Russia is currently repairing the pipeline.

In reaction to your arguments.

- Why would Russia burn her cards? Having her hand already on the gas tap and both options "turn-on" or "turn-off' is far more valuable than having no options. To scare the Europeans it suffices to turn-off not blow-up. The blow-up-North-stream narrative has already long been the well-recorded US official policy.

- Sanctions blocking the return of the gas turbine from Canada is a legal force majeure.
