As U.S.–Iran tensions surge, Tehran’s shadow network is stirring across the region. Iran-aligned militias in Iraq have unveiled fighters volunteering for “suicide operations,” while Yemen’s Houthis tease fresh attacks on shipping. The dramatic moves come just as USS Abraham Lincoln and U.S. strike groups close in on Iranian waters. Washington has issued new red lines, demanding Tehran halt nuclear escalation and rein in its proxies. Iran, meanwhile, accuses the U.S. and Israel of fueling unrest and vows resistance.
