US strikes have damaged Iran’s nuclear infrastructure, but recent assessments suggest they have not resolved the underlying strategic problem. Tehran’s capacity, material stockpiles and restricted international access leave Washington facing a prolonged confrontation rather than a clear settlement.
Attempts by the administration of US President Donald Trump to end the conflict in the Middle East have not produced a decisive outcome. Military pressure has damaged Iranian facilities and raised the cost of escalation for Tehran, but it has not brought the war to a durable close or removed the nuclear issue from the centre of the confrontation.
The central question remains Iran’s nuclear programme. According to a recent Reuters report, US intelligence assessments indicate that Iran’s estimated timeline to build a nuclear weapon has remained broadly unchanged since last summer. Analysts cited in the report assess that Tehran would need roughly nine to 12 months to produce a nuclear weapon, should its leadership decide to do so.
That assessment is significant because it follows the June 2025 attacks on Iranian nuclear facilities, including Natanz, Fordow and Isfahan. The US operation, known as Operation Midnight Hammer, was presented by the White House as a major success. However, subsequent reporting and expert analysis have pointed to a more limited strategic effect. The issue is no longer only whether buildings and centrifuge halls were damaged, but whether Iran’s nuclear material, technical expertise and ability to reconstitute its programme were eliminated.

The distinction matters. Strikes can destroy infrastructure, but they cannot easily remove know-how, trained personnel, dispersed equipment or hidden stockpiles. The International Atomic Energy Agency reported in February 2026 that Iran had not provided the agency with the required reports or access to facilities affected by the June 2025 attacks, or to the nuclear material associated with them. Without such access, the IAEA said it could not carry out its safeguards obligations in relation to those sites.
This lack of verification has strengthened the uncertainty surrounding Iran’s real position. The IAEA has been unable fully to confirm the status of highly enriched uranium produced before the attacks. The agency could not verify the whereabouts of about 440kg of uranium enriched to 60 per cent, material which, if further enriched and weaponised, could be sufficient for several nuclear weapons.
Iran continues to deny that it seeks a nuclear weapon and maintains that its nuclear programme is civilian in character. However, its accumulation of highly enriched uranium, restrictions on verification and refusal to provide full access to affected sites have left Western governments with limited confidence in their ability to assess Tehran’s capabilities or intentions.
For Tehran, time may now be the main strategic asset. Iran does not need to achieve an immediate breakthrough to strengthen its negotiating position. It needs only to preserve enough capability, uncertainty and leverage to ensure that any future talks take place under conditions favourable to its interests. In that sense, the conflict has not frozen Iran’s nuclear programme so much as moved it into a more opaque phase.
For Washington, the result is a strategic dilemma. Further military action could inflict additional damage, but it may not resolve the core problem unless the enriched uranium stockpile can be located, secured or destroyed. Such operations would carry considerable risks, including wider regional escalation and possible disruption to energy flows through the Gulf.
The Trump administration therefore faces the limits of coercive policy. Military strikes have demonstrated US reach and inflicted physical damage, but they have not produced a verified end to Iran’s nuclear capacity. Nor have they yet delivered a political settlement capable of stabilising the wider Middle East conflict.
