This little problem didn't just crop up. It's been going on for a long time. 

Trump got famous for a book he wrote years ago called The Art of The Deal.

The game the Kim dynasty has been playing is quite different. If they wrote a book it would best be titled The Art of The Shakedown.

Now after decades of work on their part its a thousand times worse because they have nukes.

The warnings about this go back as far as George Bush, the elder.

Clinton told us he had made a deal, read that paid them off, to stop it. Only it didn't and the North Koreans popped their first test nuke in 2006.

North Korea wants a pallet of cash and goods and the pressure will be to give them what they want. 

Like I said, it's a very old game. 

Dane-Geld

-Kipling

It is always a temptation to an armed and agile nation
  To call upon a neighbour and to say: --
"We invaded you last night--we are quite prepared to fight,
  Unless you pay us cash to go away."

And that is called asking for Dane-geld,
  And the people who ask it explain
That you've only to pay 'em the Dane-geld
  And then  you'll get rid of the Dane!

It is always a temptation for a rich and lazy nation,
  To puff and look important and to say: --
"Though we know we should defeat you, we have not the time to meet you.
  We will therefore pay you cash to go away."

And that is called paying the Dane-geld;
  But we've  proved it again and  again,
That if once you have paid him the Dane-geld
  You never get rid of the Dane.

It is wrong to put temptation in the path of any nation,
  For fear they should succumb and go astray;
So when you are requested to pay up or be molested,
  You will find it better policy to say: --

"We never pay any-one Dane-geld,
  No matter how trifling the cost;
For the end of that game is oppression and shame,
  And the nation that pays it is lost!"
