The Russians didn't need to blow up their own pipeline to cut off the supply of oil to Germany. Good grief. That makes absolutely no sense. They would just cut it off. If there were any doubt, Biden himself confirmed that if Russia invaded Ukraine that the US would "end" the pipeline. And do you think the US intelligence agencies would still have no evidence that the Russians did this? That would be quite an operation to pull off at sea.

But the Russians do need to blow up the pipeline, instead of just shutting off the gas, if their intentions were to:
a. Cut the Germans off of this supply of gas
and to:
b. Tell the Germans, and the rest of the world, "Watch out. Don't push us too far. We are capable of anything."
Why not blow up the pipeline and announce what Russia did?
Why have many mysterious deaths, like people considered not loyal to Putin falling out of high windows? Clearly intended to intimidate others. But not announce what Russia did?
Because sometimes its best if people know what Russia did, without an explicit confession.
