What to know about Iran nuclear facility Trump may strike

Key Points:

• President Donald Trump has threatened to bomb Iran's underground nuclear facility at Pickaxe Mountain, signaling a potential escalation in U.S.-Iran tensions amid ongoing U.S. military strikes on Iranian targets.
• Pickaxe Mountain, located near the Natanz enrichment plant, is a heavily fortified underground site believed to be intended for nuclear centrifuge assembly and possibly weaponization activities, with construction accelerating since U.S. strikes on other nuclear sites.
• Iran has condemned the threats and attacks as violations of international law, warning that any U.S. strike on Pickaxe Mountain would provoke a powerful military response targeting American and allied interests in the region.
• An interim agreement signed in June halted military operations and reopened the Strait of Hormuz, but left unresolved the long-term management of the waterway and Iran's nuclear program, leaving the situation fragile and prone to renewed conflict.
• Experts remain uncertain about when Pickaxe Mountain will become operational or if Iran will pursue large-scale centrifuge assembly there, given recent damage to its nuclear infrastructure and ongoing international pressure.
