God I hate security agencies of all kinds. Lots of power and zero accountability. They should be regulated by some UN-level treaty or banned entirely.
What I meant was more like a world-wide WMD ban, some multilateral agreement, and I used UN more as a proxy of “international level”.
The only plausible route I imagine is if the non-WMD states put massive resources into countermeasures (e.g. missile interceptors or thwarting nuclear terrorism).

And the big boys with the nukes will sit on you hard.
And if one country keeps their nuclear program, who's going to do the punishing? Sanctions don't work. Saying you're going to ban nukes is pointless dreaming. Why stop there? Why not endeavor to ban wars as well? Just wave your magic wand and ban all the bad things out of existence.
This is the same argument that gun nuts use, despite massive evidence to the contrary.
Maybe you can say instead that executive branch is too powerful by inference, and special services are just their instrument projecting this power, but I think that’s not the whole picture. By design, such services become a semi-independent branch themselves, and iirc they are not really rotated, at least on low-to-middle levels.
