An Iranian academic lays out a dire warning: if the US bombs Iran's civilian infrastructure again, Iran will wreck the Gulf oil states' infrastructure and trigger a global depression — bad for everyone, framed as Iran's deterrence.

• The US and Iran are back in open conflict, with Trump threatening to hit power plants and bridges near Tehran and blaming Iran for Houthi attacks on Saudi ships.
• Iran's warning is blunt: strike its infrastructure and it will destroy the oil and desalination plants of Gulf states hosting US forces.
• In desert countries in July, wrecking water and power would force mass evacuations — including Saudi Arabia — and choke off oil for months or years.
• The claim is this would crash energy markets and spark a global depression worse than the 1930s, dragging down the US economy too.
• Iran says it is not seeking talks; the internal debate is only whether it should have hit the US even harder, not whether to negotiate.

Outlook: Expect continued brinkmanship over the Strait of Hormuz, with any US strike on Iranian infrastructure risking a wider war and a spike in oil prices.
