Korean specialist Kong Dan Oh has a unique insight into North Korea.
Oh was born to North Korean parents and has spent her life studying the misfit nation.
She argues that the best way to change North Korea, and "end the darkness" as she calls it, is to use the truth.
"Only true knowledge and information will rescue North Koreans," she says in her book "North Korea: Through the Looking Glass."
"We have to have a more consolidated and coordinated and comprehensive information warfare," she adds, "so the North Koreans (can) make their own fate."
