Want a good charity to support the beleagured folk in North Korea? You could do worse than "Love North Korean Children" a charity established by a British Korean man who is establishing bakeries to supply food directly to children in impoverished areas. Not only is it feeding children who otherwise would struggle to get sufficient nutrition, but it is also giving them positive contacts with the outside world. It is not food with state propaganda, and does not get diverted to the military or the party.
The more of that positive foreign contact the better.
