It really kinda' does. Haven't had (m)any bombings I can recall near-ish to me, but arson (generally targeting black churches, historically, though I guess they'll get around to leaning more towards mosques, sooner or later) isn't exactly unknown.
Interestingly, Iran did sign that UN thingy wanting to ban nuclear weapons, though that's probably a choice loaded with politics (as it'd be a dig at the US) than actual policy. So, hard to tell if they're actually sincere in not really wanting to build nukes.
Eh... they probably are, but only insofar as they can maintain the possibility of breakthrough. It's kinda' the best of both worlds; the deterrent given by the possibility of nuclear retaliation if someone decides to go existential threat on 'em
and the room to leverage not actually going through with getting the capability in negotiation.
It'd possibly be different if nuclear powers weren't habitually taking massive dumps all over their back yards, though. Most even remotely relatively sane powers these days (and, by and large, iran counts as that well enough) don't really
want to have to deal with having the atomic hot potato sitting in their back pocket -- they'd much rather have the civil power generation and whatnot and call it a day, because gods know that's better for the budget in almost every situation they're going to actually encounter -- but when you have other nations that both have it and are causing messes around you/the world, it gets real beneficial to have it.
Or in other words, when you look around and see pretty clearly that the only folks that get much respect when it comes to MAD (i.e. avoidance of things like land invasions, overt domestic sabotage, etc.) are the ones that can join in, well... it starts looking like the only way certain other groups (*coughUSRussiaEUChinaetccough*) are going to stop being quite so casually willing to shit on you and everything around you is if you got the bomb. So you want the bomb, or at least the threat of having it, to keep other actors from going quite so far as they'd be otherwise willing to.
