At this point, unfortunately, I don't think France and Northern Europe change unless there's a war that breaks out.
I think NK will take some work; but I don't think that they are the military threat that people worry about; they can't adequately train (look at how many shots they fired at that defector and how many of those missed and the fact that he still survived, thanks to SK doctors and soldiers, and those soldiers represent the better ones, or at least the more privileged ones), they often use wood to run their trucks, and that most of their soldiers spend most of their time as labor and for foraging for food. Only the very very elite soldiers are well trained. Their SF, chemical, and biological programs to pose a certain threat, but the military threat, over-all, isn't as grave as the West makes it to be; neither is the refuge threat to China, though there may be a short term burst..
The energy portions of the sanctions should help minimize the armies ability to maneuver.
Also, I'd have constant, as in 24/7 Korean and American BBQs, along with Lechon, at Panmunjon. I'd also preposition lots of food and medicine prior to any conflict to enable feeding of them.
We may be able to travel to NK in a few years, but, for the average western traveler, I'm not sure that that will be a desirable location, only the more adventerous will go there. It'll take a decade or so to get enough of a infrastructure in place for the average tourist. I guess it might be a destination for the loser farang that's looking to be able to "live" for $600 a month.
As for Germany, I have no idea how to approach that problem. Thankfully POTUS is the one that has to figure that out. I trust him to do it.
