Iran and the Bomb: How Close Are We to War?

Every headline about nuclear war with Iran comes back to one number: 440 kilograms of uranium enriched to 60 percent, last verified in June 2025. This explainer follows that number through the eyes of a nuclear inspector. It covers what is documented, what is estimated and what is only claimed. It also explains why "a nuclear strike" can mean three very different events, and what to do if one ever happened near you. Information current as of November 2, 2026. Events are moving quickly, so check the latest reporting. Narration is a synthetic (AI-generated) voice. Illustrations are illustrative and not to scale.
