Why Pickaxe Mountain could become Iran’s next nuclear flashpoint - analysis

What Happened

On July 13, 2025, US President Donald Trump threatened to 'take out' Iran's Pickaxe Mountain nuclear facility while simultaneousy stating 'We see no activity there,' reflecting a long-standing US and Israeli assessment that the site, built deeper than the Fordow facility destroyed in June 2025's Operation Midnight Hammer, is not yet operational and poses no current threat. However, a July 2025 Wall Street Journal report and CNN story claimed Israeli intelligence informed the US that Iran has moved thousands of centrifuges and enriched uranium to Pickaxe Mountain, contradicting earlier confidential briefings to the Jerusalem Post that the facility remains a future, not immediate, concern. The Jerusalem Post has been unable to verify these new claims despite attempts, noting that as recently as June 30 the Israeli defense establishment did not view it as a priority. The discrepancy raises the possibility that the facility could now be treated as a current threat, prompting a US or Israeli strike.

Key Actors

Why It Matters

Pickaxe Mountain's depth challenges US and Israeli aerial strike capabilities, raising the spectre of an Iranian 'zone of immunity' if operational. Conflicting intelligence about the site's status could trigger a preemptive strike, escalating US-Iran tensions and risking broader conflict, especially after Trump's public threats and the recent destruction of Fordow. The situation tests the credibility of intelligence assessments and the threshold for military action in a volatile standoff.

Watch For

Clarification from US and Israeli officials on whether nuclear assets have indeed been moved to Pickaxe Mountain; satellite imagery or IAEA verification of activity at the site; any Trump administration or Israeli ultimatums or strike authorizations; potential diplomatic off-ramps or ceasefire talks that could refocus attention on neutralizing enriched uranium stocks over the facility itself.
