The bottom line, even if a nuclear weapon as big as the largest North Korea has ever tested were to impact squarely on Manhattan, the vast majority of New Yorkers would survive the initial blast. A strike would devastate central Honolulu but leave many suburbs intact. If the missile misses a city center even by a small amount, the number of initial casualties plunges dramatically.

And you can call your arborist, if he's still alive and if the phone system is still working, and cancel that tree-trimming you had planned. Win-win!
