> Those were Soviet nukes, physically located in Ukraine but not controlled by it, same as any French/US nukes stationed in Germany would not make it a nuclear state.
This is not an accurate comparison.
It's not that Russia had nukes in Ukraine and withdrew them. Many of the Soviet soldiers manning them were Ukrainians and stayed behind. Much of the infrastructure for maintaining the Soviet arsenal was also in Ukraine and had to be rebuilt in Russia. The situation was more akin to if the US broke up and Louisiana (which has a lot of nuclear warheads stationed in it) is dealing with whether they are now a nuclear power, or if they need to hand them over to South Carolina or something.

Russia is the single legal successor of the USSR, so all Soviet nukes became Russian nukes, regardless where they were located. So after the USSR broke up, Russia did have nukes in Ukraine and withdrew them.
Legal succession is mostly irrelevant and more complicated than that. Russia had operational control because it had taken physical control of the ex-Soviet command and control systems which were in Russia, and hence had the launch codes, etc.
To be fair, Russia becoming the single successor of the USSR wasn't a foregone conclusion in the early 1990s. There wasn't relevant precedent of a country dissolving I think -- Yugoslavia was still battling it out, Austria-Hungary was too long ago.
It was an explicit decision by both CIS and UN. Russia took USSR's seat on UNSC two weeks after USSR was dissolved, and that happened in 1991. Budapest Memorandum was negotiated 3 years later, by which time this was already a firmly established thing.
