Ukraine was the 3rd largest nuclear power in the world, and is famous for it’s history with nuclear energy.
The issue here is that them starting the enrichment process is grounds for the start of WW3, and they wouldn’t complete the effort in time to offensively defend themselves. You’d have to give them entirely complete nukes and even that would just mean it’s nuke launchin time for a number of folks.
I see this a lot which is wild to me because I feel like S4 felt like it finally was real Star Trek but just rushed and some of the damage to some characters couldn’t be fixed. All the major plot points that make Enterprise relevant to Star Trek happen in S4.
I’m curious where you put Discovery? That is the one I struggle the most with. My primary issue there is that for me I have to actually like and want to be invested in a character but as far as I’m concerned 10 episodes in to Discovery if the ship blew up all hands lost the Federation I can’t think of anyone I’d feel sad for. Enterprise though has Trip and Phlox who are S tier, a few fantastic guest stars, and no character that is bottom bin material to me no matter how much fanfic quality writing they tried to force on T’Pol.
