Did you see the story about classified info regularly being sent to random people in Mali because they send it to .ml instead of .mil by mistake?
But yeah honestly I doubt it matters what he knows, having him parade Infront of people saying how awfull the west is would play well to the home crowd, they can pretend to have gotten great secrets from him and he'll be given all the luxuries North Korea can spare...

First I would bang on a neighbor's door and pay them to follow me with a camera then run into the fairly nearby motorbike shop and yell 'quick I'm doing a Mr Beast challenge I need to spend a million dollars in the next half hour!' all four guys working would jump at it especially if I said 'give yourself 10% commission on each one'
The only other shop near that isn't just groceries is a wedding dress shop so I guess while they're getting the paperwork ready I'd run in and buy their most expensive white gowns so that we could ride in style - though the train might get caught in the chain...
Oh and I'd run into the pub and tell them to ring up as much as possible before the time runs out so we can all go there after to relax.
