nuclear enrichment is extraordinarily expensive and really not all that great of a deterrent when you have them. just look at fairly recent tussels between india, pakistan and china. Russia was invaded and didnt nuke ukraine.
Ukraine and weapons of mass destruction
Ukraine, formerly a republic of the Union of Soviet Socialist Republics (USSR) from 1922 to 1991, once hosted Soviet nuclear weapons and delivery systems on its territory.[1] The former Soviet Union had its nuclear program expanded to only four of its republics: Belarus, Kazakhstan, Russia, and Ukraine. After its dissolution in 1991, Ukraine inherited about 130 UR-100N intercontinental ballistic missiles (ICBM) with six warheads each, 46 RT-23 Molodets ICBMs with ten warheads apiece, as well as 33 heavy bombers, totaling approximately 1,700 nuclear warheads that remained on Ukrainian territory.[2] Thus Ukraine became the third largest nuclear power in the world (possessing 300 more nuclear warheads than Kazakhstan, 6.5 times less than the United States, and ten times less than Russia)[3] and held about one third of the former Soviet nuclear weapons, delivery system, and significant knowledge of its design and production.[4] While all these weapons were located on Ukrainian territory, they were not under Ukraine's control.[5]
In 1994, Ukraine agreed to transfer these weapons to Russia for dismantlement and became a party to the Treaty on the Non-Proliferation of Nuclear Weapons, in exchange for economic compensation and assurances from Russia, the United States and the United Kingdom to respect Ukrainian independence and sovereignty within its existing borders.[6][7] Almost twenty years later, Russia, one of the parties to the agreement, invaded Ukraine in 2014 and subsequently also from 2022 onwards.

Btw, reference [5], used to justify the absurd claim that those weapons were in Ukraine's territory but not under its control, goes like this:

So it's basically the words of a UK MP assuring his audience that, nooo, don't worry, Ukraine doesn't control its WMD.
After all if your country is too small, it may be worthless to have nukes that probably would be destroyed by neighbors on launch...
(My bet would be: max one day)
Just need one flight from Pyongyang. Why suggest involving a major power given that you’ve just laid out the strategic need for nuclear weapons to deter interference from… major powers? Your post lacks coherency.
- it costs money and attention
- good is not the same as perfect (there are some casualties from time to time)
They protect against being "policed" by big world countries.
Eg. if Ukraine still had nuclear weapons, Russia would not have been invading them (or are they "protecting" them, as promised when they took their nuclear arsenal for destruction?). If Iran or Iraq had nuclear weapons, they would not have been bombed by US.
Israeli nukes are the main reason we haven't had regime change in Tel Aviv at the hands of a Turkish/Egyptian/Saudi/Iranian coalition. Israeli nukes are why Iran has had to settle into a pattern of slow, distant, annoyance via proxy forces (which lack a capability for existentially challenging the IDF).
