Why would the people of North Korea tolerate the current government other than to resist invasion?
The Kim family has done a lot for the people in the DPRK, and is generally very well liked. It's not all sunshine and rainbows, but a lot of the problems stem not from the current DPRK leadership but the international (read: US) sanctions placed on them. Compared to the hypercapitalist hellscape of SK, the work-life balance in the DPRK seems downright utopian. Prior to the US invasion, the Korean peninsula was fairly unified in their support of socialism.
The people would certainly welcome peace, I just don't know how that is possible while the threat of the USA looms. People like to portray them as an aggressive country, but they have never done anything to another coountry except threaten to defend themselves.
Oh yes, definitely that doesn't happen in any of those "civilized" western countries right? Nobody making up things like "North Koreans have no word for love" or "We push trains to work every day".
