I feel like with North Korea you won't get nearly as many people who would lose out in the new regime such that you'd see an insurgency launched. There are very few people in the country whose lives would not improve under basically any possible government who would intervene there (whether South Korea, or an American, Chinese, or Russian occupation).
A few generals and high-ranking apparatchiks and their families would rush the Swiss embassy and try to get shuttled out of the country, but most people would be glad for the change.
