Agreed that the other photo is dodgy, but there's not actually that much difference between it and yours. North Korea at night is largely dark, either way.
The photo you posted indicates only one metropolitan area (Pyongyang). In the GlobalSecurity photo, there are several metros lit up (one speck of light from space is considerable amount of people).
The photos can be dramatically different depending on year or a time of day. Street lighting in DPRK is not organic or municipal, and they often have been short on energy.
Whether they can or can't build the infrastructure means nothing. They built this plant in 18 months (allegedly), what do you think is going to come up at the UN?
They've got two responses - 1) no this has always been there, your inspectors are incompetent. As everybody, even you, knows NK doesn't have the ability to do this kind of project normally (IE outside funding our last ditch effort - regardless it's out of the norm) or 2) Yes we built this plant in 18 months to enrich uranium, the power plants are under construction now and the grid will be ready for when the plant commences operation.
This is so out of character that the response is either "yeah right dumbass, like that happened" or "dumbass, the rest is easy".
I think a plant for refining weapons grade nuclear material counts as their war machine.
Granted, the rest of their infrastructure sucks, but I don't think their dumb enough to build a plant without power. And they do know how to keep power running. Does anyone actually think the Great Leader lives in some un-lit hovel?
Technically, the Great Leader doesn't live anywhere. He died in 1994, although he retains his official status as head of the North Korean state. He is presently located in a museum near Pyongyang.

All the resources are going into their war machine.
If could/would build infrastructure, it would have been done long ago.
There won't be a coup, they are all brainwashed.
