Kyiv could rapidly develop a rudimentary weapon similar to that dropped on Nagasaki in 1945 to stop Russia if the US cuts military aid, it has been suggested
With regards to Ukraine: IHave69xibucks is right. A nuke is more useful as leverage than an actual weapon. Russia will absolutely be more generous to Ukraine during negotiations should Ukraine develop a nuke. 1 nuke in Moscow wouldn’t bring down the whole country, but it’s not nothing either.
Hence the threat of MAD is used as a valuable tool for leverage during negotiations. Might as well have a nuke to scare Russia into attenuating their strikes and force them to agree to more of Ukraine’s demands.
