Ukraine had the people and means to make them operational. It also currently has the means to create new nuclear weapons with uranium mines, research reactors and nuclear physics expertise. Also expertise to create ICBMs. Russia has ensured that no nuclear nation will ever disarm because treaties are just a piece a paper and world will just sit back and do nothing when it is violated.

That's just a pure speculation, could or could not. Ukraine is a semi-failed state with an ongoing civil war(and was for decades), it can't create anything new unfortunately. Improve some old Soviet technology maybe, but ICBMs... The discussions should not be about weapons but on how Ukraine can pull itself from the current hole it dug in.

"Ukraine is a semi-failed state with an ongoing civil war(and was for decades)" It is a pure lie, there was no conflict in 1991-2014. What's a semi-failed state? How do you define it?

"how Ukraine can pull itself from the current hole it dug in" What do you mean by digging a hole?
