I cannot recall language from any world leader at the UN podium that comes even close.

"If [the United States] is forced to defend itself or its allies, we will have no choice but to totally destroy North Korea," he told world leaders, causing a stir in the hallowed hall of diplomacy.

"Rocket Man is on a suicide mission for himself and for his regime." 

But to speak of wiping out a country of 25 million people? No.
