Should Post-Regime Collapse Refugees Be Allowed to Settle In South Korea?

The mass refugee issue is why I believe if the regime was to collapse the DMZ should remain in place to stop a mass population movement to the South.  It would be up to the ROK to quickly move and distribute aid to the North which would help mitigate a mass population movement:

U.S. experts have urged South Korea and the U.S. to jointly devise measures to improve assimilation of North Korean defectors to other countries in the event of a North Korean collapse.

Olivia Enos and Bruce Klingner, researchers at the conservative U.S. think tank the Heritage Foundation, released a report titled “Next Steps for Human Rights in North Korea” on Tuesday.

The report said the U.S. must adopt a multi-pronged strategy that acknowledges the two important stakeholders in the human rights debate: people inside North Korea and defectors outside the country.

It said the U.S. and South Korea should strive to remedy problems before a potential Kim Jong-un regime collapse and the humanitarian crisis that would follow.

The researchers said that if the North were to collapse, as many as three-point-65 million North Koreans could look to resettle in South Korea.

They said that such a large-scale humanitarian crisis would threaten the stability of South Korea, unless a comprehensive assimilation plan was created well in advance.   [KBS World Radio]
