Now reason without water, aka Israeli + GCC desalination. Iran with shit water situation is still less existentially water stressed. Iran 5% vs others 80/90%+ dependency on desalination = once Iran demonstrated survivable regional strike complex, they own the top end of escalation ladder that can take out everyone with them while coming out least harmed.

This not to mention, relative to US performance / conemps, i.e. going back to standoff munitions, there's not really enough discretionary high end munitions to take degrade all Iranian infra vs Iran has enough in reserve to take out all regional desalination. Nevermind US expending 1000s more TLAMs / JASSM(ER)s leaving it unprepared for any other near peer conflict. Reminder Iraq was 20% size of Iran, and so far US+Israel only flew ~20% of sorties via Iran than it has Iraq. Even factoring in precision munitions, US would have to expend more munitions than it has to actually cripple Iran on par with Iraq.
