Realistically, we have exactly one reason for nukes: Oncoming Celestial Object Deterrence. For that you need only a handful of reliable nations with weapons which have large yields.
I would say the US, France, and China are the acceptable nations.
Britain has had security issues, Russia threatens it’s Western neighbors at an alarming rate with them, Israel’s are a political landmine, and both India and Pakistan keep egging toeing the line in Kashmir.
