If I were imprisoned in that hellhole, I’d want to escape my misery through drug addiction too.
I just hope the South Koreans aren’t too idealistic, and/or too eager to reunify under any conditions. If and when reunification happens, it MUST be under the total control of the South. It cannot be a joining of equals, but rather the South taking over the North on its own terms. Anything less than that will lead to disaster.
