You also need to maintain vectors, at least functioning ICBMs, which cost quite dearly. And Russia had much more ressources than Ukraine at the time, by the way.
Ukraine absolutely had fleet of functioning ICBMs and strategic bombers. Unlike russia, Ukraine didn't declare bankruptcy.
And pretty sure people who built those ICBMs and strategic bombers would have no issue maintaining them.
USA didn't pressure Ukraine into giving up nukes, at the same time bankrolling russian nuclear program for 'security' reasons.
