Maybe blowing up the Nordstream pipeline wasn't such a smart move, after all.

Do we know with any degree of certainty who was actually responsible for sabotaging the pipeline?

It seems all evidence points to a Ukrainian op performed by a small team and minimal amounts of explosives.

Ukraine is also the only country which had clear motive and no real repercussions if found out (because already at war with Russia).
