Not especially. Their other facilities were being bombed routinely by Israel (along with infrastructure).

So they have medical grade uranium facility under a mountain? If that’s all they need, wouldn’t it be easier to just purchase it from a third party instead of investing billions of dollars hiding from Israel?

They have a military base under a mountain, not a uranium enrichment facility.

Building military defenses against crazed, genocidal, racial supremacists who routinely fire missiles at your country seems more like sensible forward planning to me rather than evidence of a guilty conscience.
