- IAEA warns it cannot fully verify Iran's nuclear activities due to disrupted monitoring systems
- Military strikes damaged Natanz facility entrances but core underground halls remain intact
- Iran holds 440 kg of uranium enriched to 60%, near weapons-grade but weaponization takes time
As fighting intensifies in the Middle East, the future of nuclear diplomacy with Iran is increasingly uncertain. The most immediate concern is transparency. In its latest assessment, the International Atomic Energy Agency (IAEA) warned it cannot fully verify Iran's nuclear activities after monitoring systems were disrupted and access to some facilities became uncertain. At the same time, the agency confirmed that entrance structures at the underground enrichment complex in Natanz Nuclear Facility were damaged in recent military strikes, complicating inspections further.
Together, those developments highlight a key reality: when nuclear talks collapse during a war, oversight weakens before anything else.
The First Thing That Changes: What Inspectors Can't See
The most immediate shift after diplomatic breakdown is not a nuclear explosion - it is the loss of monitoring.
Inspectors from the International Atomic Energy Agency rely on cameras, seals and physical inspections to track nuclear material. But damage to facilities and restricted access can quickly reduce that visibility.
The agency warned recently that it cannot currently verify the full status of Iran's enriched uranium stockpile following disruptions caused by military action. According to reporting by the Associated Press, inspectors have struggled to confirm the exact quantity and location of key nuclear material.
In nuclear diplomacy, uncertainty itself is a major risk.
1. Enrichment Could Rise But Weapons Still Take Time
Iran already possesses uranium enriched to 60% purity, close to weapons-grade.
In its latest report, the International Atomic Energy Agency estimated that Iran holds roughly 440 kilograms of uranium enriched to that level, enough that further enrichment could theoretically produce several nuclear weapons.
But reaching weapons-grade - roughly 90% enrichment - is only one step.
Building a functioning nuclear weapon requires designing a warhead and integrating it with delivery systems such as missiles. Those steps take time and are closely monitored by intelligence agencies.
The gap between 60% and 90% is technically smaller than earlier stages of enrichment - but it still requires additional processing.
2. Military Strikes Can Delay - Not Erase - Nuclear Progress
Recent strikes during the ongoing conflict have targeted infrastructure linked to Iran's nuclear and missile programmes.
Satellite analysis cited by Reuters shows damage to entry buildings at the underground complex in Natanz Nuclear Facility. The International Atomic Energy Agency said the core underground enrichment halls appear intact.
History suggests such strikes usually delay nuclear programmes rather than eliminate them entirely.

Facilities can be rebuilt, equipment relocated and expertise cannot be destroyed.
3. Sanctions and Pressure Escalate
If negotiations collapse, Western governments often respond with sanctions.
The United Nations Security Council has previously imposed sweeping restrictions targeting nuclear technology transfers and financial networks linked to Iran's programme.
Sanctions are designed to push Tehran back to negotiations without triggering immediate military escalation.
4. Diplomacy Moves Into the Shadows
Even during conflicts, nuclear diplomacy rarely disappears.
Indirect negotiations - often mediated by regional actors such as Oman or European governments - have historically kept communication open between Washington and Tehran.
These channels allow adversaries to signal red lines and explore compromises without public political pressure.
What to Watch Next
Analysts say several indicators will determine how the crisis evolves:
- Whether Iran increases enrichment beyond 60%
- Whether the International Atomic Energy Agency regains inspection access
- Whether indirect talks resume through mediators
If diplomacy collapses entirely, the nuclear issue becomes far harder to monitor.
But history suggests negotiations rarely vanish. They simply become quieter - and more urgent.
