I think you are missing my point. The Nukes were built by the soviets, but after the breakup, Russia had control of them in Ukraine. In order for Ukraine to take full possession, they would have to fight through Russians at military bases.

I agree with that, my point is that the Ukrainians had the technical capabilities to seize control. And they chose not exercise that option. Besides, why did only Russia, of the 15 post-Soviet states have to retain control over all the stockpile?

The answer is probably because the alternative was too scary for the west. Better to keep dealing just with Moscow.
