US Launches New Strikes on Iran as Concerns Mount Over Undeclared Pickaxe Mountain Nuclear Facility and Continued IAEA Access Denial

July 15, 2026 · 🔴 Risk: High

⚖️ Two accounts of the same story

Where sources agree

There is a clear consensus among Western sources and international bodies (IAEA, UN) that Iran is continuing to advance its nuclear program, particularly at undeclared or inaccessible sites like Pickaxe Mountain, while simultaneously refusing international inspections. This is happening amidst an escalating military conflict with the US and Israel.

Where sources differ

Iran consistently maintains that its nuclear program is peaceful and that facilities like Pickaxe Mountain are for centrifuge assembly, not enrichment. They also argue that UN Resolution 2231 has expired, justifying their refusal of IAEA access to certain sites.

The ongoing military conflict between the US and Iran, coupled with Iran's continued refusal of international nuclear inspections and advancements in its deeply buried nuclear infrastructure, significantly increases regional instability and the risk of nuclear proliferation. The lack of transparency regarding Iran's nuclear program, particularly at sites like Pickaxe Mountain, makes it challenging for international bodies to assess the true scope of its capabilities and intentions.

📌 Key developments

US Central Command (CENTCOM) launched a new round of strikes against Iran on July 15, 2026, targeting military sites near the Strait of Hormuz to degrade Iran's ability to attack commercial shipping.
Western intelligence agencies continue to express concern over Iran's deeply buried Pickaxe Mountain (Kuh-e Kolang) facility, suspected to be an undeclared uranium enrichment plant or centrifuge manufacturing site, with satellite imagery indicating ongoing construction since 2020.
Iran maintains its refusal to grant International Atomic Energy Agency (IAEA) inspectors access to its damaged nuclear facilities, including Fordow, Natanz, and Isfahan, asserting that UN Resolution 2231 has expired.
The IAEA has lost 'continuity of knowledge' across all of Iran's declared nuclear facilities since US and Israeli strikes began in February 2026, hindering its ability to verify the production and inventory of centrifuges, heavy water, and uranium ore concentrate.
Negotiations between Tehran and Washington remain deadlocked, with the Memorandum of Understanding (MOU) signed on June 17, 2026, having been declared 'over' by President Trump on July 8, leading to resumed military exchanges.

💡 Why it matters

The escalating military conflict, coupled with Iran's continued refusal of international nuclear inspections and advancements in its deeply buried nuclear infrastructure, significantly increases regional instability and the risk of nuclear proliferation. The lack of transparency regarding Iran's nuclear program, particularly at sites like Pickaxe Mountain, makes it challenging for international bodies to assess the true scope of its capabilities and intentions, posing a serious challenge for non-proliferation efforts and future diplomatic solutions.

👀 What to watch

Any further statements or actions from the US or Iran regarding military operations or the naval blockade.
New intelligence or satellite imagery concerning the Pickaxe Mountain facility or other Iranian nuclear sites.
Any developments in diplomatic efforts or potential for renewed negotiations, despite the current deadlock.
