Russian state television has no doubt who is unpredictable enough to bring the world to war in the North Korean crisis, and it's not the reclusive communist dictator Kim Jong Un.

According to Dmitry Kiselyov, the Kremlin's top TV mouthpiece, the riskiest is Donald Trump, the man Russian officials and propagandists hailed just a few weeks ago as just the kind of leader the world needed.

In the latest sign of the Kremlin's abrupt about-face on its erstwhile American hero, Kiselyov pronounced Trump "more dangerous" than his North Korean counterpart. "Trump is more impulsive and unpredictable than Kim Jong Un," he told viewers of his prime-time Sunday "Vesti Nedelyi" program, which earlier this year carried paeans to Trump for his pledge to warm up relations with Russia.
