I'm not saying it's a good idea. I def would rather not have more nukes about if it can be avoided.

Just maybe not stupid. When you consider Ukraine was pretty much the home of the USSRs weapons tech, People there developed most of the nukes and the MIG aircraft. That is likely why in part Russia want it. The expertise is still very much there as we saw with Ukraine MIGs compared to Russia. They have been upgrading since the 90s.

I'd guess if any nation was able to throw this together as a MAD Like defence in time for trumps potential withdrawal. It would be these guys.

Also given how close to Moscow, They are. The tech would really only need to be 1945 level for Russia to recognise the risk of continuing.
