Not sure why you played the race card. This has to do with countries that are not that particular stable, are more or less dictatorships and most certainly have designs on nuclear weapons.
If Iran actually developed nuclear weapons, nearly every country of any size will absolutely do the same shortly after. Saudi Arabia, Egypt, Syria, hell even Jordon might. Is dumb to think they won’t and maybe even more so to think they won’t get used for ideas of expansion within our lifetime. There moment one is used, the whole world is involved.
I don’t care how unfair you might think that is. Not happy they exist but there are only a few countries I trust to have them. And I am not so silly to think said countries could not have them when countries like China and Russia are nuclear armed.
