The same was once said of Saddam Hussein. Where is he now? And could still live if not put itself above God. The same fate awaits Kim Jong-UN.
And much of his army was a bunch of tubby chancers. The North Koreans are indoctrinated from birth. They're on a never ending war footing and they believe that the US has always been the ultimate evil.
They're a short cruise from Seoul and they have enough cannon fodder to throw away to cause an insane amount of damage.
Cannon fodder won't help. The Americans will destroy targets from afar. When they destroy all the infrastructure, the army will surrender itself. You forget how they fled Saddam's army. The main thing that Trump doesn't.
