War in Iran and the nuclear non-proliferation regime: a perspective from Pakistan

Sufian Ullah

On 28 February, the United States and Israel launched joint missile strikes and airstrikes targeting several Iranian cities. This included a decapitating strike that assassinated the country’s supreme leader, Sayyid Ali Khamenei. The apparent objective of these strikes was to fuel regime change in Tehran (as US President Donald Trump framed the situation speaking to the Iranian people: ‘When we are finished, take over your government. It will be yours to take’) and conduct preventive counter-proliferation measures. The principal disagreement between Washington and Tehran – evident before and during their latest round of nuclear talks – has concerned the latter’s uranium enrichment levels, and monitoring mechanisms. Trump’s hardline stance with respect to Iran’s nuclear compliance – a consistent feature of both his presidential terms – has gradually narrowed the scope for negotiated de-escalation.
Diplomacy falters

In February 2026, high-level talks between the US and Iran, facilitated through third-party mediation, were underway in Oman and Geneva. These sought to reconcile the United States’ and its allies’ demands for caps on Iran’s enrichment levels with Tehran’s insistence on its legal rights as laid out in the Treaty on the Non-Proliferation of Nuclear Weapons (NPT).
