Right stealing nukes you cannot immediately operate as a 0-year old nation, to me it doesn't seems like an incredibly bright idea in a world where the existing nuclear states doesn't want anyone else to get nukes too.
And in any case it's was not simply removing the safety devices on the weapons, you need to be able to target the ICBMs at Russia, which Ukraine could not do:
> In fact, the presence of strategic nuclear missiles on its territory posed several dilemmas to a Ukraine hypothetically bent on keeping them to deter Russia. The SS-24s do not have the ability to strike targets at relatively short distances (that is, below about 2000 km); the variable-range SS- 19s are able, but Ukraine cannot properly maintain them. [...] the SS-19s were built in Russia and use a highly toxic and volatile liquid fuel. To complicate matters further, targeting programs and blocking devices for the SS-24 are Russian made. The retargeting of ICBM is probably impossible without geodetic data from satellites which are not available to Kiev.
> Cruise missiles for strategic bombers stored in Ukraine have long been 'disabled in place'.[...] As with ICBMs, however, retargeting them would be impossible for Ukraine, which does not have access to data from geodetic satellites; the same goes for computer maintenance.

So Ukraine did not have usable weapons at hand. But it did, and does, certainly have the capacity to build entirely new weapons, if given time.
> stealing nukes you cannot immediately operate as a 0-year old nation
Agreed. But nobody was invading Ukraine in 1994.
The weapons were seen as a security liability. In reality, they were bargaining chips.

To be clear, Kyiv made the right decision given what they knew in 1994. Non-proliferation was in vogue. America and British security guarantees meant something.
If Kyiv knew what we know today, that the Budapest security guarantees were worthless from each of Washington, London and Moscow; that wars of conquest would be back; and that non-proliferation would be seen through the lens of regional versus global security, it would have been a bright idea to demand more before letting them go, or at least to drag out negotiations so Ukraine could study the weapons and maybe even extract some samples.
> SS-24s do not have the ability to strike targets at relatively short distances (that is, below about 2000 km)
Again, having the nukes would give Kyiv leverage. At a minimum they'd have HEU and a proven design to study.
And again, don't undervalue bullshitting in geopolitics. If Kyiv said they have a short-range nuclear missile, it would not be credible. But would it be incredible enough to green light an invasion?
The US and Russia would have done a joint invasion under UN flag if Ukraine tried to steal the nukes dude, it's downright embarrassing to pretend that's the sort of thing you can do unpunished.
And doing that for some design info is really not worth the risk: just recruit some soviet weapons designers, for sure there are Ukrainians in that project already.
Oh, please, please, exclude Romania. I live close to our nuclear power plant. I'm scared of our incompetence as it is, without trying to make any nukes.
