Or how closed we are to them? There is no media unbiased about them in the west. But I do know you can travel to NK and see for yourself.

That said, it is easier to know things about Portugal than NK. They are definitely doing something to hide information. I'm just trying to say that any image based on the media from non friendly country is bound to be wrong. No matter how much different sources you have.

My understanding is that tourists in North Korea only see what the government of North Korea wants them to see.

Here's one (admittedly potentially biased) source that claims as much:

"Tourist travel to North Korea is only possible as part of a guided tour. Independent travel is not permitted. If you are not prepared to accept severe limitations on your movements, behaviour, and freedom of expression, you should not travel to North Korea." [0]

No you cannot. You'll be chaperoned everywhere and only shown things they want you to see.

We are not closed to them. The relationship in terms of how much each country sees inside the other is highly asymmetric here.

you can travel to NK, but you might end up like Otto Warmbier and come home a couple years later braindead. (he stole as a propaganda poster a souvenir, but brain death after a year of brutal torture seems.. extreme.)

you're also not allowed to travel without a guide.

also, given the videos I've seen taken by tourists when they've been able to sneak away from their minders, NK does not look very happy.
