> The status of Iran’s nuclear sites (and more importantly, its stockpile of enriched uranium) is anyone’s guess at this point. It’s likely that no one truly knows, not even the Iranians.
The project is dispersed and hardened enough that a single attack probably wont' be a decisive blow.
The surprising thing is that Iran doesn't have an atomic bomb yet. Enrichment is the hard part. Building an A-bomb from enriched uranium is not that difficult. The technology is 80 years old and most of it is well known. It's no worse than building, say, an auto engine from scratch, something racing shops do routinely.
H-bombs are another matter. Those are hard.
