President Donald Trump has repeatedly threatened to attack Pickaxe Mountain, an underground Iranian facility reportedly used for nuclear activity.
The escalating tension represents a critical flashpoint in the Middle East, as the U.S. seeks to prevent Iran from expanding its nuclear capabilities through secretive construction projects.
Pickaxe Mountain is located on the south side of the Natanz nuclear enrichment complex [1]. Trump said the site represents a nuclear threat that the United States must neutralize. These threats have been issued over recent days, coinciding with what has been described as the 10th [2] straight day of hostilities between the U.S. and Iran.
While the U.S. identifies the site as a nuclear facility under construction, the Iranian government denies any nuclear activity at Pickaxe Mountain [3]. This disagreement over the nature of the site persists as the U.S. evaluates potential targets for military action.
The current tension follows previous military engagements in the region. According to reports, the bombing of Natanz during Operation Midnight Hammer occurred in 2025 [4]. Trump said the United States is not finished with Iran, suggesting that the underground facility may be among the next targets for strikes.
Security analysts note that the subterranean nature of the Pickaxe Mountain site makes it a more difficult target than surface installations. The facility is designed to protect sensitive equipment from aerial bombardment, a strategy Iran has employed to safeguard its nuclear program from previous U.S. operations.
“Trump said the site represents a nuclear threat that the United States must neutralize.”
The focus on Pickaxe Mountain signals a shift toward targeting hardened, underground infrastructure. By threatening a site that Iran denies is nuclear, the U.S. is testing the limits of Iranian deterrence while signaling to the international community that it views subterranean expansion as a red line for nuclear proliferation.
