If I was in a power position, I could theoretically channel this water into my own private reservoirs and locations like private land, bunkers, etc to weather a disruption, and blame Iran and it would be really hard to validate.
I mean if I was in a power position I would have also disrupted those in positions who would be validating me, made journalism much harder and have algorithms with LLM-enhanced astroturf accounts running to label any questioning of the official narrative as conspiratorial or tin-foil hat.
I would probably be on sites like this downvoting people who said things like this. Yes. That's how I would do it. edit: Oh I might even consider channeling that water to my data center friends!
