Ukrainian nuclear weapons aren't a credible threat to Russia, for the same reason Russia's aren't to Ukraine: It isn't under an immediate threat of being wiped out, just losing territory. I think this is aimed more at the United States, trying to pressure them into keeping up or increasing aid with the threat of nuclear proliferation (as Japan, Taiwan and Saudi Arabia have done). There is also the possibility that in a Trump administration, loss of US aid could turn the war back into an existential threat where nuclear weapons could be used.
There's actually a very good reason why Russia operates like that - mutinies. If you give junior officers authority, in a political system like Russia's where the leadership's legitimacy is purely based on power and self-interest, they might decide they'd rather be the ones in charge. This was perfectly demonstrated when they gave a military unit autonomy, and that resulted in the Wagner mutiny.
Unfortunately, the supreme court has zero checks and balances, and recently has been willing to make partisan political rulings, so it may well strike it down to help Republicans.
It's been well reported on that Russia doesn't work like that, with junior officers unable to use initiative and the whole system being very slow to respond to changing events. The reason it operates like this was shown when they did try having a more independent unit, which resulted in the Wagner Group mutinying.
