I've heard analysis that a significant proportion of middle east water and food supply - in the form of desalination plants, and cargo through the Strait of Hormuz - is within reach of Iran's capabilities. The logic is that you use this to collapse middle eastern economies which blocks the flow of the investment from Arab states into AI infra that is propping up the US economy.
Iran is unlikely to target food and water without being further backed into a corner, since the escalation would mean reciprocal strikes (possibly independently by the KSA air force) on the Kharg and Bandar Abbas export terminals, which have so far avoided being targeted.
> is within reach of Iran's capabilities
Analysts have been playing fast and loose with this phrase. Within reach assuming no air defenses and able to be struck are separate. I believe Iran could hit this infrastructure if it were undefended. It’s not practically able to due to air defenses. (Iran already targeted the small Gulf states’ airports. Given how much food they import by air, that’s an attempted blockade strike.)
