Washington signals a strike on Iran's hardened underground nuclear site as the eleven-day campaign's costs and casualties climb.
Intelligence Lead
President Trump has signaled an imminent US strike on Pickaxe Mountain, Iran's fortified underground nuclear facility near Natanz, as the war enters its most dangerous phase yet. Tehran has warned that any strike on its nuclear infrastructure will be treated as a formal expansion of the conflict, raising the risk of retaliation against US forces and regional partners already absorbing near-nightly missile and drone attacks. Defense Secretary Pete Hegseth's disclosure that the war has cost $37.5 billion, a figure congressional sources say understates the true total by tens of billions, underscores how far the campaign has outrun its original scope.
Situation Report
US Central Command confirmed the eleventh consecutive night of strikes against Iranian targets late Tuesday, part of a campaign aimed at breaking Tehran's blockade of the Strait of Hormuz. Iranian President Masoud Pezeshkian said Monday that Iran considers itself engaged in a "full-scale war" with the United States, and warned Iranians they will have to accept the conflict's consequences.
Intelligence assessments reviewed by allied services indicate Iran relocated enriched uranium stockpiles and advanced centrifuges to Pickaxe Mountain, a facility buried roughly 100 meters beneath a mountain near the damaged Natanz enrichment site, following earlier strikes in the campaign. Trump said Tuesday the United States would hit the site "very heavily, pretty soon." Tehran has responded that any attack on its nuclear facilities constitutes an expansion of the war.
Regional states are absorbing the fallout. Kuwait, Bahrain, and Jordan each reported intercepting aerial attacks today, evidence that Iranian retaliation is no longer confined to US assets but is spreading across Gulf and Levant air defenses. A US service member was killed in northern Iraq during a controlled explosion to neutralize an Iranian attack drone, the latest in a string of American casualties since the campaign began.
On Capitol Hill, Hegseth defended a $67 billion supplemental funding request before the Senate Appropriations Committee, telling lawmakers the campaign has cost $37.5 billion to date, up from a $25 billion estimate given in April. Congressional sources and an internal Pentagon assessment obtained separately by reporters put the true figure between $80 billion and $100 billion once base repair, aircraft replacement, and munitions replenishment are included.
Background & Context
The current campaign traces to the killing of Supreme Leader Ali Khamenei in a joint US-Israeli strike on 28 February, which opened a period of open hostilities after years of a "no war, no peace" standoff that Khamenei himself had privately urged Iranian leadership to resolve. Since then, US and Israeli operations have targeted Iran's nuclear infrastructure, air defenses, and naval assets in the Gulf, while Tehran has responded through missile barrages, drone strikes, and efforts to constrict shipping through the Strait of Hormuz.
Pickaxe Mountain has emerged as the campaign's central remaining objective. Satellite imagery reviewed by independent analysts, including CSIS, has flagged signs of renewed nuclear-related activity in Iran even as its above-ground facilities remain degraded, lending weight to assessments that Tehran is attempting to preserve a breakout capability underground and out of reach of conventional strikes.
Analysis & Assessment
A strike on Pickaxe Mountain would mark a qualitative escalation distinct from eleven nights of standoff against conventional targets. Given the facility's depth and Tehran's explicit warning that such an attack constitutes war expansion, planners should assess elevated probability of retaliatory strikes against US basing in Iraq, Syria, and the Gulf states, alongside intensified attempts to disrupt shipping through Hormuz.
The widening gap between the Pentagon's public cost estimate and the higher internal assessment is likely to sharpen oversight fights in Washington independent of battlefield developments, and could constrain the administration's freedom of action if the supplemental funding request stalls in Congress.
Regional interception activity by Kuwait, Bahrain, and Jordan signals that Gulf states are being drawn into a sustained air-defense posture that outlasts any single strike cycle, raising the likelihood that a Pickaxe Mountain operation triggers broader multi-state defensive mobilization rather than a contained bilateral exchange between Washington and Tehran.
