Reader takeaway

How we got here
The Pickaxe Mountain site sits near Iran’s Natanz enrichment facility. Since 2025, activity has increased amid regional tensions and counter-narratives about Iran’s nuclear ambitions.

Our analysis
Bloomberg reports that the IAEA has not yet inspected the tunnel complex but notes activity; CNBC highlights Trump’s warning and CSIS’s assessment of increased construction; The New York Post cites CSIS findings on deep underground fortification. All pieces point to a rising tempo of activity near Natanz and Pickaxe Mountain, with US reactions shaping the narrative.
