I’m not so sure that nuclear weapons would help in these kinds of regional conflicts against Russia. It’s not that Russia officially invaded Ukraine (although in practice it did), but it stirred up local population (of largely Russian ethnicity) and then gave them logistical support and protection. So, if Ukraine had nuclear weapons, what would it do with it? Strike Russia, who has many more nuclear warheads, and stronger anti-nuclear protection? Nuclear weapons are for USA, China, Russia, and maybe France/Europe, because they are not going to use it. Maybe Israel, whic is so tiny and surrounded by rrivals, that it has no choice but to have something to scare the neighbors with. Maybe India, because it’s big enough. For everyone else, nuclear weapons are a liability, because if they ever use it, they are going to be wiped out by the big boys for not obeying...
