North Korea is not shut out on google earth or google maps.  I don't know why this tik tok video claims it is.  Looking at it now.

As an aside, I have what I think is as rare map.  A Defense Mapping Agency Kosan, Korea (North Korea) map, SHEET 3223 IV 1:500000 scale. 

I was showing this map to an ex South Korean Army officer.  When he realized that this map was a section of North Korea, he freaked out a little.   Told me that if this map was found in my possession in South Korea and I was not in the U.S. Army, I would be arrested!  This was back in 1986.  Hopefully that would not happen today with access to google earth on the internet.
