Do we need any more reasons why North Korea and its backer, China, are evil?
There should be no quarter given to China or Russia, the very countries that have conspired to keep Korea separate since its liberation. Hold them responsible for allowing everything that has gone on up until this point. I'm sure the survivors of the North Korean regime will take care of Kim Il-Sung's fat progeny themselves (Satan has a good grasp of Il-Sung's love handles as we speak).
As for the South Koreans' morally lazy government, well... can one teach empathy?
