Iran's facilities are being monitored by the IAEA. There's nothing for them to acknowledge. This headline makes it seem like they're confessing to something, but it was done openly and in plain view of the nuclear monitors.

People seem to think that nuclear enrichment is a loading screen, now that they've done 84%, they're going to be close to getting to 90%. That's not how it works. Iran has been able to enrich 90% for a decade at least. They have never done so. Most people think that their nuclear program is on some sort of breakneck race to get to 90% and start building a bomb...that's just not true.

If Iran wanted to build a nuclear weapon they could kick out the IAEA and build one tomorrow, like North Korea did. Or they could do what Israel India and Pakistan did when they wanted nukes, and simply never signed the NPT.

They have no reason to invite the IAEA into their country while simultaneously trying to build nuclear bombs under their nose. Any country in the world that wanted to do it could do it easier.
