there was a multi, yes. That multi was also found to have recently applied to IRON, and being accepted into NATO. Then the multi was used to try to stir up tensions between TOP and NSO...
These alliances being targeted are simply not coincidental.
The intentions of the individual probably will not be ever revealed. However, the evidence shows:
1) There was a multi
2) that multi was used in a manner that was detrimental to the securities of alliances that were enemies of RoK.
3) the individual was a former official of Rok.
Lets say that he decided to abandon RoK, and turn over to the other side for his own reasons. Why keep his other nation in RoK? Why use his multi for stirring up trouble between TOP and NSO? why not apply to numerous other alliances that were not antagonistic toward RoK?
With this evidence, I believe that there is beyond a reasonable doubt that the multi was used for spying and infiltration.
