Lol kyivpost really? Did you just give up on any attempts at finding any resemblance of an unbiased source? Sounds like desperate attempt at a damage control, could we get a full transcript of the speech in its original, shouldn't be too hard to translate and see what was really said
The source is not Kyiv Post, the source is the president's office.
Given that Ukraine doesn't have nukes and Russia does and Putler never did any "damage control" on his threats to use them, the accusation that Zelensky is starting a nuclear war is about as absurd as all the other Kremlin fantasies.
