States without nukes, that once had nukes or nuclear programs but gave them up through diplomacy:
Pre-2003 Iraq
Pre-2011 Libya
Pre-2014 Ukraine
States with nukes, that refused to give them up through diplomacy:
North Korea
So if you're a rogue state, which would you rather be?
You forgot South Africa, which developed 6 nuclear weapons in the late-1970s (?) through the late -1980s in the first group (possibly with the help of Israel, and part of the reason they gave them up so the blacks couldn't have them when Apartheid ended, IIRC).
So many people forget they had them as well.
