It probably is a type of extortion. He is no fool. All he has to do is look around the world. Those countries which have abandoned their nuclear programs under pressure from the west have been toppled. Libya agreed to a program in return for lifting of trade embargoes. He was regime changed. Iraq lost their program in an attack and never restarted. He was regime changed. Pakistan and India developed programs and grew closer to the US. And notably Iran audaciously refused to give one inch, not even to reduce their “remove Israel from the map” rhetoric and we gave them a peace treaty. The then asked for ransom and we paid it!
So why would Rocket Man back down now?
Obama is no longer in charge
You make some good points ... except Trump was not President when all those things happened. Kim can see that Bush II invaded two countries including the toppling a leader and Trump appears more aggressive than Bush. So I think Kim will go only so far with Trump.
“So why would Rocket Man back down now?”
He won’t back down but won’t strike first either.
What will end up happening sooner or later is that he will get a lot of people killed unintentionally and then it will be game over for him.
That's why he's the Muslim Traitor.
Literally, pallet loads of cash to finance international terrorism, all financed by you and me!
