Those weren't their nukes to begin with, they had no capability to maintain them nor to use them without the codes. Giving them up was not only the only option for them but also in retrospect best for the rest of the world since US could easily coup them twice.
Nice of you to wish nuclear armed banderites to the world. As a Pole i wouldn't be able to sleep at night. Not to mention those minorities in Ukraine that would be sleeping eternal sleep after banderites end with them.
