First, is it even possible?
The answer is yes, absolutely. There is enough (non-weapons grade) spent civilian nuclear reactor fuel to get enough radioactive materials. Much more importantly, there is plenty of “know how” amongst Ukrainian scientists and engineers. Besides, bringing in radioactive materials or specialists is something the AngloZionist Hegemony could do. Did I mention plenty of starry-eyed Ukronazi politicians daydreaming on camera about how to nuke Russia and kill as many Russians as possible?

I've always felt that zelenskyy is blackmailing them for cash because he helped with the impeachment phone call hoax and has knowledge (and participation in) various deeply illegal activities in Ukraine. Possibly election related, bio weapons, money laundering etc.. its a "cash or we go public" situation...
It's the only thing IMO that's makes sense..
