An ex‑IDF Iran expert has warned that the US‑Israeli air campaign that killed Ali Khamenei and installed his more hard‑line son Mojtaba may end up doing the opposite of what Trump and Netanyahu promised—pushing Tehran from “threshold” status into a full‑blown race for the bomb. With Iran’s nuclear sites hit, 440 kilograms of highly enriched uranium still at large, and Mojtaba openly vowing revenge and hinting he is not bound by his father’s anti‑nuke “fatwa,” the expert argues that regime‑change warfare weakens the system but strengthens its determination to go nuclear, especially after Washington walked away from a deal that would have capped enrichment in exchange for sanctions relief.
