Is there any way an outside person can somehow help the cause of human rights protection for North Koreans? I understand that it's the place where the worst things on Earth are happening in our times, but have no slightest idea if it's anyhow possible to help the oppressed people... edit: Wikipedia suggests e.g. this: http://www.libertyinnorthkorea.org/ http://www.libertyinnorthkorea.org/ (via https://en.wikipedia.org/wiki/Liberty_in_North_Korea https://en.wikipedia.org/wiki/Liberty_in_North_Korea, via https://en.wikipedia.org/wiki/Human_rights_in_North_Korea#International_reaction https://en.wikipedia.org/wiki/Human_rights_in_North_Korea#In...) as a charity rescuing NK defectors hiding in China into US. That said, can one anyhow confirm if they do what they advertise? Still, I plan to try donating regularly to them anyway now (which may be cumbersome without a credit card), unless I manage to find something looking even better anyhow. Another option from Wikipedia: https://en.wikipedia.org/wiki/North_Korea_Strategy_Center https://en.wikipedia.org/wiki/North_Korea_Strategy_Center ("sent over (...) 400 radio sets (...) into North Korea" -- I recall people living under communist regime in the past as mentioning that radio is important for giving a glimpse of a different, better world; also from "NKSC's History": "While [the future founder of NKSC] Kang Cheol Hwan lived in North Korea he remembers being influenced by foreign South Korean radio broadcasts which helped him decide to defect from the country after having lived 10 years in the Yodok Political Prison Camp.") Also, I'm not from US.
