Trump threatens to destroy Iran's 'Pickaxe Mountain' nuclear facility

President Donald Trump has threatened to destroy Iran's underground 'Pickaxe Mountain' nuclear site near Natanz, which remains undeclared to the IAEA.

• Trump said in a Monday television interview that the US would "eliminate Pickaxe Mountain" and likely strike it "relatively soon."
• The facility consists of tunnels buried 80–100 meters beneath granite rock, making it one of Iran's most fortified nuclear sites.
• Iran has not officially declared the site's purpose, and IAEA inspectors have not been granted access.
• US intelligence assesses the site as a potential secret uranium enrichment facility; Iran says it is for assembling and manufacturing centrifuges.
