This is one of those situations where developments have shown the Doomsday Clock to be nothing more than a silly exercise in bad marketing.
By their calculations, and keeping the clock analogy with its implied 24hr day, we are already 1437/1440th away from nuclear obliteration. So what does it matter if the US gives the bomb to Donald Trump? What are they going to do…raise that percentage from the current likelihood of 99.7916% to, what, 99.8611%? Even as an analogy: what the hell does that even mean: N Korea, with its few weapons, gets us to a 99.79% chance of humanity’s doom, and DJT with his thousands of bombs, only increases this threat by 6/10th’s of 1%? How do those numbers make any damned sense?
If this idea had any validity and was, in fact, a measure of this groups concern about the direction of current events, they wouldn’t keep the clock within the range of 98.81%-99.81% of “midnight”.
