The lack of nukes isn't because of restriction of information. That lasted about as long as it took to leak the info to Soviets. It's far more complicated than that.
The US (and other nations) is not too friendly toward countries developing nukes. There are significant threats against them.
Also perspective is an interesting thing. Non-nuclear countries like Iran and (in the past) North Korea that get pushed around by western governments probably wouldn't agree that restriction is for the best. They would probably explain how nukes and the threat of destruction/MAD make people a lot more understanding, respectful, and restrained. Consider how Russia has been handled the past few years, compared to say Iraq.
(To be clear I'm not saying we should YOLO with nukes and other weapon information/technology, I'm just saying I think it's a lot more complicated an issue than it at first seems, and in the end it kind of comes down to who has the power, and who does not have the power, and the people without the power probably won't like it).
Every single member of the UNSC has facilitated nuclear proliferation at some point. Literally every single one, without exception. It's not really a core objective.
