Do you really have to ask that? Even if one were to believe this is due to Trump (I don't), NK have NEVER kept their word on ANYTHING dealing with nuclear capabilities.
IMHO sanctions did bring NK to the table.
Kim Jong-un had 2 priorities when assuming power aside from purges.
Make it impossible or extremely difficult to attack the Regime- Nukes gives him that.
Changing the economy allowing more free market as they have done with some farm production that began in 2012. If you recall at the end of the USSR they were doing the same thing and food production increases were substantial
Food supply- 2017 drought and flooding which has caused a massive shortage of food. Famine is a threat to stability within the Regime
For now it beats the hell out of giving NK a bloody nose.
I think NK is considering that Trump may order an attack on NK. If the US did, aside from causalities that could run into 10's millions, the Regime would fall.
And the Regime are survivors first and foremost.
China would be on board as they do not want nukes in SK, or Japan developing their own.
Recall the Cuban Missile crisis- US promised not to invade Cuba.
Do I think they will give up the nukes- No.
If they agreed to smaller numbers of Nukes that would entail invasive checks on any facility, by the US and UN thru NK.
Destroying all long range missile facilities and missiles. Again with invasive inspections, including destroying any chemical agents and delivery systems.
I realize that chemical weapons can be delivered by artillery.
Any inspections would need to be permanent to prevent any start of production.
Yes fissile grade materials can be easily hidden.
Do I think that will happen. No.
Do I think Trump will order a preemptive attack on NK. Better than 60-40 he will. Mattis and Tillerson have slowed McMaster from presenting a bloody nose plan to Trump.
Please do not bring up I/P discussion outside the I/P forum.
