US President Donald Trump has issued a fresh warning that the United States could strike Iran’s heavily fortified Pickaxe Mountain nuclear-linked site “very soon”, reopening one of the most sensitive fronts in the escalating US-Iran confrontation. Trump said Washington was closely watching activity at the facility and reiterated that preventing Iran from obtaining a nuclear weapon remains the central objective of the US military campaign.
Located near the damaged Natanz uranium-enrichment complex, Pickaxe Mountain contains deeply buried tunnel systems built into the mountain. The site has attracted particular attention because its underground construction could make it significantly harder to assess or neutralise from the air. What is actually inside the facility remains uncertain, with international inspectors unable to independently verify its current status.
Why This Threat Is Different
A strike on Pickaxe Mountain would carry a different strategic calculation from attacks on conventional military targets. The facility’s hardened underground nature means an attack could become an attempt not merely to destroy infrastructure, but to prevent Iran from rebuilding parts of its nuclear programme.
However, uncertainty itself creates risk. Iran has denied conducting nuclear activities at the site, while US officials have raised concerns about possible reconstruction efforts. Without independent inspection, competing intelligence assessments could drive military decisions with potentially serious consequences.
The threat also comes as Washington and Tehran remain locked in a wider confrontation involving military strikes, sanctions and tensions around the Strait of Hormuz.
The Bigger Geopolitical Risk
For Trump, threatening Pickaxe Mountain reinforces a policy of maintaining maximum pressure on Tehran while keeping the possibility of a negotiated settlement open. The danger is that another strike could push the conflict into a new cycle of retaliation.
The central question is therefore not simply whether the US can target Pickaxe Mountain, but whether doing so would reduce Iran’s nuclear capability or accelerate a broader regional escalation.
