Signals, Red Lines, and Collision: The Israel‐Iran Spiral and US Intervention

open access: yesMiddle East Policy, Volume 33, Issue 2, Page 5-23, Summer 2026.
Abstract The Iran War erupted in February 2026 without UN authorization, and Washington's rationales—Iranian nuclear ambitions, missile capacity, and proxy threats—map more closely onto Israeli than US security interests. Why have we seen two major conflicts between these belligerents in less than one year?
