Wow..!
That. Totally. SUCKS.
Yes, a sweet bargaining chip —for them.
Getting complicated.
Always just remember a thing or two about North Korea negotiating tactics when it comes to the issue of hostages (kidnappees). They use these to MAXIMUM benefit and with aplomb. Expect a pathetic, weakneed kowtow trip by Gov. Bill Richardson or Jimmy Carter to Kaesong within a month to give away the whole store, such as withdrawl of all American forces from the region in return for the Industrial site hostages they will release peace meal, a few at a time, and keep a few for safe keeping and good measure, and claim they are missing and suspected of dying in a boating accident.
