According to recent reports, Israeli intelligence says Iran moved thousands of fission devices to a secret underground site in Pickaxe Mountain near Natanz, as stated by sources. This took place in 2025. The centrifuges join others earlier buried in tunnels across the Alborz mountains. Israel provided these information to The Wall Street Journal. The International Atomic Energy Agency has so far not made any statement yet. US and Israeli leaders now look at likely military steps after Donald Trump said in 2024 that Iran’s nuclear program could press America to act.
