Yeah but what about the Balrog? They'd have that to contend with.
And maybe... in fact I'd bet that creatures like Smaug could survive a nuclear blast even relatively nearby and probably even radioactive fallout, and just in case, they'd also know where every single cave in Middle Earth is, could quickly find cover before being exposed too much.
You can mathematically group the people in your life in such a way so that half of the people you know are stupider than the other half.
I swear to fuckin' god, man, politics make it real easy to tell who goes in which half. It's not a perfect method, but it works at least 85% of the goddamned time.
Because so many trump voters are low-information, rabid and impervious to fact and/or reason. They will vote orange even if he shoots someone on Fifth Avenue to death, or if there are 32-or-whatever felony indictments/verdicts.
Meanwhile, many potential Democrat voters are also low-information in their own way - impressionable, fickle and with little memory retention, they seem unable to act upon a clear and present danger until it punches them in the goddamned face (and by then of course it's too late), somehow have normalized the orange threat and are easy prey to an algorithm pushing a "both parties are the same" divide-and-conquer propaganda.
The difference between a parasite-laden excrement chip cookie and a raisin oatmeal cookie, "But I wanted chocolate chip! bOtH cOoKiEs ArE tHe SaMe!"
Now that's the kind of mathematical thinking that leads to shit like imaginary numbers, [∞(∞)/∞-1] or TREE(3), and let's not forget the Mandelbrot and Julia sets.
We've had one nuclear winter, yes, but what about the second nuclear winter?
