North Korea has found good material to attack President Donald Trump: Michael Wolff's bombshell new book, "Fire and Fury."

The North's main Rodong Sinmun newspaper said Thursday the book's sales reflect what it calls "rapidly surging anti-Trump sentiments in the international community."

It says the book's popularity "foretells Trump's political demise."

Last summer, Trump threatened to unleash "fire and fury like the world has never seen," triggering a furious response from the North.

Trump and North Korean leader Kim Jong Un have since traded bombastic threats of war and crude insults against each other.

Trump called Kim a "Rocket Man" on a "suicide mission." Kim called the American president "the mentally deranged U.S. dotard."
