The Middle East is home to about 42% of global desalination capacity. Reliance on this water varies significantly by country: Qatar and Kuwait rely on desalination for 90% or more of their municipal water, while Saudi Arabia (70%), Oman (86%), Bahrain (85-90%), and the UAE (42-90%) also depend on it for the vast majority of their drinking water. Desalination plants supply roughly 80% to 85% of Israel's domestic drinking water.
Iran could and would target these vulnerable plants.
Even a "temporary" stoppage at a few plants would be adequate to decimate a nation's population. Five days max without water and people die
Israel has 5 desalination plants. Knock out 2 for a couple of weeks and Israel collapses
Now let's consider Israel's nuclear plant
Iran could hit it with a few missiles and boom it's like a nuclear weapon went off
Keep in mind that when Israel and America attacked the Natanz nuclear facility Iran responded with an attack on the residential areas around Israel's plant, intentionally showing they had the capacity to hit the plant without actually hitting the plant which would have been a major escalation.
Now let's consider LNG in the ME
March 18"19, 2026: Further Iranian attacks delivered significant structural blows to the Ras Laffan complex, destroying infrastructure that accounted for nearly 20% of global LNG exports.
If you don't understand the devastation what would result from Iran permanently destroying 20% of the world's LNG I don't know what to say.
