And all that with what motivation? To harm themselves? Harm own economy? Or as KGB likes to say "to frame poor ruzzians"? As opposed to the country who had clear motive (avoid financial sanctions for stopping gas supply, which they actually did already)? And which had an easy and non sci-fi tool to do it? (maintenance payloads inside the pipes)
Come on, stop with the propaganda. Or at least find some fresh one. I have an idea for you - that Ukraine actually bought Prigozhyn wholesale. How's that for a delusional idea? Great, right? Better than cocaine used at Ostankino.
