What Is Pickaxe Mountain, Iran’s Underground Nuclear Site That Trump Is Threatening?

As the Middle East teeters on the brink of another devastating war, President Donald Trump’s threat to attack Iran’s underground nuclear site, Pickaxe Mountain, has sparked a heated debate about its true nature and significance. While some experts warn that Pickaxe Mountain is crucial for Iran’s nuclear ambitions, others see it as a pretext for US aggression.

At the heart of the issue lies Trump’s assertion that Tehran must never acquire a nuclear weapon. This stance dates back to his presidential campaign days and has been a constant drumbeat in his dealings with Iran. However, few have questioned what this obsession reveals about America’s own nuclear policies and its willingness to confront Middle East complexities.

Pickaxe Mountain is no ordinary site. Located 220 kilometers south of Tehran, it sits near one of Iran’s primary enrichment facilities and has been shrouded in secrecy since construction began in 2020. Satellite imagery analysis by the Institute for Science and International Security suggests that the facility appears to be “very deep,” with tunnel entrances potentially reaching depths of at least 100 meters.

The US government claims Pickaxe Mountain may be used as a nuclear enrichment plant, while Iranian officials insist it’s a secure storage facility for nuclear materials. The International Atomic Energy Agency has been unable to independently verify Iran’s centrifuge capacity and production since 2021, leaving open the possibility of secret stockpiles.

The origins of Pickaxe Mountain are linked to mysterious events plaguing Iran’s nuclear program over the years. In 2020, a fire broke out at Natanz, one of Iran’s primary enrichment facilities, which Tehran claimed was caused by sabotage. This incident marked a turning point in US-Iran relations, with Washington seizing on it as evidence of Iranian perfidy and launching targeted strikes against Iranian nuclear sites.

The legacy of these attacks continues to shape the present. The Natanz facility suffered significant damage again in February 2026, with IAEA inspectors discovering that tunnels at the site were likely being used for storing enriched uranium. This context raises questions about Trump’s latest threat: is Pickaxe Mountain a target of opportunity or an attempt to sow chaos and destruction?

The puzzle surrounding Pickaxe Mountain is complex and multifaceted. While some experts warn that Iran may be hiding nuclear secrets, others see it as a desperate attempt by Tehran to salvage its faltering nuclear program. What’s clear is that Trump’s obsession has created an atmosphere of heightened tension in the region.

If Pickaxe Mountain is used for secure storage, what does this say about Iran’s commitment to transparency and cooperation with international inspectors? Conversely, if it’s being used as a nuclear enrichment plant, what does this portend for non-proliferation efforts in the region?

As tensions escalate, one thing remains certain: Pickaxe Mountain has become a focal point for US-Iran relations. The question now is not whether Trump will follow through on his threat but rather what the consequences of such an action will be. Will it lead to further escalation and bloodshed in the Middle East, or mark a new chapter in US-Iran diplomacy? Only time will tell.

Pickaxe Mountain has become a symbol of the destructive forces defining US-Iran relations. As we hurtle towards another crisis point, it’s worth recalling the words of James Acton: “The best one can do is try to collapse the tunnel entrances.” But what about the very real risk that this action could unleash a nuclear nightmare upon the world?
