Agreed - as unequal as it may appear to those who see the issue purely through the lens of fairness (if some countries have nuclear weapons, why not everyone else) - the entire purpose of the non-proliferation framework is precisely to prevent that outcome. The objective is not universal equality in nuclear capability. It is to prevent new nuclear states from emerging, particularly in highly unstable regions, by restricting enrichment to civilian levels only - roughly 3–5% - and keeping any weapons-relevant capability under strict international oversight. Iran moved well beyond that threshold. With its enrichment of uranium to around 60% purity, it is far beyond any credible civilian requirement and technically much closer to weapons-grade enrichment (~90%). At that level, the additional enrichment required to reach weapons-grade becomes significantly shorter. Iran already possesses advanced ballistic missile systems capable of delivering a nuclear payload. What it did not publicly possess was a nuclear warhead containing weapons-grade uranium. The concern among proliferation experts has long been that the gap between Iran’s current enrichment levels and a functional nuclear weapon could be measured not in years, but potentially in weeks, should enrichment be pushed to weapons-grade. The question worth asking is not why the US is reacting now, but why it did not react far sooner. Negotiations clearly failed. Iran exceeded the limits it had agreed to under the Joint Comprehensive Plan of Action, which capped enrichment at 3.67%, and progressively moved well beyond those restrictions. Sanctions, embargoes and diplomatic pressure were intended to prevent exactly this scenario. Yet enrichment continued to increase, stockpiles continued to grow, and the programme moved steadily closer to weapons-relevant capability. At some point the question stops being whether diplomacy should work - and becomes whether ignoring its failure simply allows the problem to become far harder to contain later.
