The escalating conflict between the United States and Iran has entered a new phase, with President Donald Trump threatening to destroy Iran's "Pickaxe Mountain" nuclear facility. Located south of Tehran, this site is one of Iran's most fortified nuclear complexes, featuring two tunnel complexes buried hundreds of meters beneath solid granite rock. US intelligence reports suggest the facility may serve as a "strategic hedge" for Iran's nuclear program, potentially housing a secret, undeclared uranium-enrichment facility. However, Tehran maintains that construction, which began in 2020, is solely for assembling and manufacturing advanced centrifuges.
