Who said it was an acceptable scenario? That’s not been suggested.
You’re saying we should belive any story that makes nuclear war sound even worse than it obviously is regardless of its scientific accuracy. Science should be objective truth not whatever serves the agenda you’re trying to push, even if it’s objectives are good.
Peer reviewed science gets overturned by other peer reviewed science all the time, the other person also had peer reviewed science so you don’t get to just wave yours and win.
And yes your agenda is very obvious, you take the side of not wanting to be in a nuclear war - I think that’s pretty much a universally agreed upon position.
However you also have another facet to your opinion which is almost as universally disagreed with as your other position is agreed with - you think that science should be falsified so it seems to provide answers which suit your social and political aims rather than it being an effort to understand the world and reach a truthful and valid conclusion.
You were very aggressive and rude to someone who did nothing more than provide more context and dissenting evidence in a discussion about science, that’s not a good way to behave.
