Western and Israeli intelligence say Iran moved thousands of uranium-enrichment centrifuges into fortified tunnels inside Pickaxe Mountain near Natanz last autumn, a relocation linked to hardening the program after June 2025 strikes. President Donald Trump, speaking at a White House meeting, signaled that the United States would strike Iran’s Pickaxe Mountain 'very soon' and 'very heavily,' marking a significant escalation as ceasefire talks appear unlikely. The site is deeply buried and potentially difficult to target with bunker-buster weapons, complicating any plan to neutralize it. U.S. options reportedly include pursuing a short ceasefire to reopen the Strait of Hormuz or launching a major joint campaign with Israel, with Trump showing a preference for a broader strike. Iran has not publicly confirmed the relocation, and Tehran maintains its nuclear program claims, while the region experiences increased attacks and volatility. The situation raises concerns about further destabilization and implications for global energy routes and diplomacy.
