In the meantime, the most damaging act of sabotage that we know of on European ground was perpetrated (it seems) by Ukrainians. Many were pointing the finger in Russia’s direction when that happened, even if it didn’t make much sense. Just saying, we shouldn’t take spooks at their word, you never quite know who is really behind covert attacks on infrastructure. At best we, the general public, can speculate. It usually takes a hell of a long time for any serious investigation to take place, if that is even going to be conclusive.
