As US and Iranian delegations prepare for peace talks, concerns are mounting over Pickaxe Mountain, an underground nuclear site in Iran. Experts suggest that this site, which is buried approximately 2,000 feet under granite, may be beyond the reach of even the most powerful US bunker-buster bombs. The US President Donald Trump has indicated that he may not extend a two-week ceasefire if negotiations fail, and has warned of securing Iran's nuclear material through 'unfriendly means' if necessary. Despite US airstrikes crippling Iran's nuclear program over the years, Pickaxe Mountain remains untouched, raising fears it could facilitate Iran's nuclear ambitions in the future. Iran claims its nuclear program is peaceful, designed to meet energy needs, but has not allowed the International Atomic Energy Agency to inspect the site, leading to suspicions about its true purpose. Experts estimate that Iran may have already stored some of its 970 pounds of highly enriched uranium at this location.
