Ukraine never had the possibility to keep its nuclear arsenal, they simply didn't have the infrastructure for it, let's not pretend they had any real choice.
The US built nukes in the 1940s. Ukraine has at least as much technical know-how and engineering infrastructure as, say, Pakistan or North Korea.
They couldn't have launched the Russian warheads as-is, but disassembly and reuse of the warhead material is another thing entirely.
