That cat has been out of the bag for half a century. There are currently over 11 thousand warheads in existence. Enough to turn every major city in the world into a smoke plume that will blanket the earth for years to come. In addition, countries don't really use commercial reactors for breeding weapons grade materials anymore. Usually they will provision reactors specifically for that job. Like the Los Alamos Savana River facility.
Also, there are a lot more ways to produce weapons grade nuclear materials now than there were in the 1970s when most of these weapons were created. The invention of lasers, high temperature superconducting magnets, higher quality centrifuge materials, and better particle accelerators have made the creation of weapons grade material way easier.
In other words, when it comes to weapons proliferation, we are so utterly screwed. Only political change will ever reduce the number of weapons in existence. Commercial power production isn't even a factor.
There aren't very many nuclear-weaponized countries in the world right now. Otherwise, the whole Iran Nuclear Deal issue would've been moot. Even Russia won't hand over nukes to Iran.
We aren't building these reactors in Iran. In fact, Iran maintains the capability to produce weapons using it's own reactors and centrifuges. It has it's own stockpiles of Uranium.
This was a response to the comment about nuclear weapons proliferation being a cat out of the bag. It's not out of the bag yet. Iran has been "nearly there" for several years already, and that's only wrt the enriched uranium, not the actual weapons.
Another important example because they're at war, Ukraine. And in the vaguely possible event of an Asian Pacific war, Japan and Australia have no nukes, but that's more by choice.
