Iran has stockpiled highly enriched uranium. Iran has ballistic missiles. You deny that?
Why is this a concern of yours
I could care less
They’re thousands of miles away
Are you scared?
OK, let's say for sake of argument that Iran was months away from building a functional nuclear weapon. Do you really believe that they would use this to stage an attack against the US, knowing that A. they would almost certainly be annihilated and B. that with a very meager nuclear arsenal, what few weapons they have would be intercepted/destroyed by US defenses regardless?
Weak nations don't attack powerful ones. Weak nations that do develop nukes or try to do so as a deterrent against being attacked. I'm not saying that a potentially nuclear-armed Iran is a great thing. However, the idea that it would be a mortal, existential threat to the US is absurd. China has many times the nukes that Iran could ever dream of, when's the last time China attacked the US?
