Simple. Stop obeying them. Die rather than submit, if they want to kill you. The regime would not last a month without the cowardly obediance of underlings. The army can't feed itself, the leaders can't even protect themselves. If they come and take your food, let them, but go to a temple and stay there, in response. When they order you to do things, look them in the eye and say "no". If they want your work, they can bloody well give you respect and decency. They can have your life at any time, it is not your soul or your integrity. Everyone dies eventually. Not everyone lives as a slave.

Very easy to say from a well-fed, comfortable Western perspective.

The people in North Korea have been brainwashed for the last 50 years. They have no access to information from the outside world. The entire society is based around worship of the Dear Lader. The propaganda machine has convinced them that there is a worldwide famine and that N. Korea is actually better off than anywhere else. If you and your family had spent the last 50 years living in that society, you would not be fighting back, either.

So, to say that these people can be expected to rise up is completely unrealistic.
