I imagine the DPRK classifies all Americans and Europeans as simply "Western imperialist dogs", or something like that. The last thing I'd be worried about when planning a trip to Pyongyang is whether the US is cool with it. I would go to nearly any other country than go to North Korea. Just doesn't seem worth it. Wouldn't feel right putting my tourist $$$ directly in the pocket of the fascist Kim regime, for that.
I went in 2012; all the villages I saw exhibited poverty, failing and non-existent infrastructure, evidence of food scarcity and some interesting evidence of long-term solid fuel shortages. That said, we didn't specifically visit them. Drove by and through
