Yea, it's really the dumbest argument I've heard in the longest time.

"Hey, I'm building a weapon that has a 5% chance of killing us all by itself, but an 85% chance of killing us all if an idiot leader gets ahold of it".

The rational response to this is "Fucking stop then". I don't get it, our reality seemingly has gone off the rails that people would argue for us getting wiped.
