That was after the war started. I thought you were talking about before that. If you ask me, Russia did what we should have done even earlier.
Ha, ok. No I was indeed talking about during the war.
It's during the war, well before the sabotage, that Europe decided -and announced- that they were going to move away from Russian energy supply.
So, if the followed through on that statement, it was only a matter of time before Europe itself would have stopped buying gas through that pipeline.
But finding new suppliers off course takes time. In the meantime, buying gas from Russia just went on. And that's when Russia started using it as a weapon by curtailing it and eventually shutting it down completely under some ridiculous pretext of "maintenance". Then they lied about how there was a problem that they couldn't fix because "sanctions". So two birds in one go:
1. economic hurt in europe due to soaring prices
2. half blackmail of lifting sanctions so they supposedly could fix their imagined problem with the equipment
There was nothing wrong off course.
It was all just "
they're going to stop buying anyway, let's be a step ahead and hurt them economically while we still can"
This is where I see the motive for blowing it up as an end-game "final" blow. First it was merely shut down and could still be reoponed. The market still had that hope. Blowing it up would take that hope away and deliver a double economic hit.
But again, I consider Ukraine a more likely candidate for the act, simply due to the evidence so far (which is nevertheless flimsy imo).
But it certainly is not the case imo that Russia had no motive at all to do it.
