Lets just hope ...
I really hope they have already evacuated the complex, wiped the servers/workstations and set thermite destruct charges on any heavy equipment they don't want the Norks to have. Because I can totally see the North Koreans just saying FU and sending troops in to secure the place ASAP, probably with the excuse that it was to ensure the safety of the North Koreans working there.
The part that really worries me is that history has shown that seemingly little things like this can be like a lit match into a pool full of petrol and cause things to heat up real fast.
I am probably wrong, and I really hope that I am.
