THE REFUGEE WEAPON:

While unhappy with North Korea’s recent nuclear weapons test, there is not a lot China can do about it. This is because North Korea threatens to unleash hundreds of thousands of desperate North Korean refugees across the border, into northern China, if China applies too much pressure. Currently, the North Koreans have pretty tight control over this border, but that could be relaxed in an instant, allowing a flood of refugees into China. To counter that threat, over the last month, China has been moving more troops and police into northern China, not just to look for existing North Korean refugees, but to man more border posts, in an effort to keep out North Koreans.

Citizens or hostages? In a regime like Kim Jong Il’s there’s no difference.
