Nuclear brinkmanship usually works. It's also incredibly dangerous. by Nate Silver
Not much to add to this one from Nate Silver:
But this certainly isn’t some sort of 13-dimensional genius move. It reflects an unchecked Commander-in-Chief who was erratic on his best days, who is 79 years old, who was boxed into a corner, who has sycophantic advisors who are mostly too afraid to challenge him, and who once bragged that he could maintain approval from his base even if he murdered someone.
