"The DPRK is once again being used for fear mongering. Fear mongering is the main reason why nobody has gone to war to end the regime. The US, UK, and everyone else in NATO loves the DPRK because "scare the populace to get what you want without revolt". "
This is nonsense, it's a completely US centric view. No one outside the US inside NATO really gives the slightest fuck about North Korea because North Korea is both completely out of range as a threat and because we're just not in North Korea's gunsights anyway. When it comes to talks about North Korea in contrast to talks about, say, Iran's nuclear programme, Europe is rarely even around the table other than perhaps to just stay in the loop and find out what's going on.
Given that I'm not sure how NK can be used for fear mongering in the UK or NATO (except the US) because there's nothing scary to us about it. I understand why some people in the US might be concerned, because the US is regularly the target of North Korea's rhetoric, but I really can't remember the last time NK threatened the UK and even if it did the threat would be entirely hollow because there's literally nothing it could do to touch us right now even if it wanted to. The same is true for the rest of Europe - NK just isn't on our threat radar over here, so it can't possibly be used for fear mongering, whatever you wish to theorise about that possibility.
NK only has limited military assets, even if it can weaponise a nuke (rather than just blow one up underground after months of preparation) it's just not going to waste one on any European nation no matter what happens so the whole "Western World Fear Mongering (tm)" conspiracy theory that lazily gets pulled out every time someone even loosely related to the Western world complains about a foreign state just makes absolutely no sense outside the US in this particular case.
I assure you, if Europe is worried about anything right now it's Russia, because Russia actually has invaded, annexed, and de-facto annexed the sovereign territory of a number of European nations in recent years (e.g. Georgia, Ukraine, Moldova). If anyone's going to fear monger the UK and other NATO states they're at least going to do it with the one country that's proven itself to be a genuine threat where there is actually something to potentially fear.
North Korea is pretty much entirely a South Korean/American/Japanese/Chinese problem. The rest of us just don't care enough for it to be possible to use it for fear mongering.
