LOL Daily Show had a show about it Netanyahu has been saying Iran will have nukes within weeks, since 2008

Facilities deep in a mountain, no IAEA access, refusal to negotiate, October 7th, ... You'd have to be quite naive to think it's all above board. (Instead of under a mountain).

They have been saying that (at least) since 1995.

Who is 'they'? United States, Israel, media outlet?

What’s the OTHER justification for a hardened nuclear program and having a pile of enriched material that can only be used for weapons?

This is the IAEA report [0], claiming enough material for 9 weapons.
