Bro I'll be real with you north Korea got fucking obliterated to the extent that they were living underground because every single building has been bombed to rubble. North Korea was definitely the victim of imperialist interference. No person in that country deserved that level of devastation.
Ehhh the Korean war is complicated. It started with Japan invading Korea and attempting to erase their history and culture. (Worth noting that America gave them the green light on this). After WW2, Korea was divided and backed by US/USSR interests on either side. It was a shitshow with everyone disagreeing how things should be run. Eventually North Korea did invade the South, though, so I guess this meme still applies. But even that fact is unclear - they claim it was retaliatory. Who knows.
