The NK’s have had 50 years of watching US/SKorean maneuvers. They’ll have files on every strategy, and considering its the defense of a peninsula, how many can there really be. Also collaborators will have sited every prepared fighting position and line of communication. There can’t be many surprises left.
The only real question mark is the willingness/reluctance of Washington to honor commitments. That’s not data they’ll get from a flash drive.
I agree.
