Unlike the "Great War"...

Exactly. The tunnels in WWI (and the American civil war) were not for attack or infiltration, they were for planting mines.
If I were a south korean, I would be very concerned about what the North were sticking in those tunnels, I think soldiers would be the least of their concerns

Today's tin hat theory - The Yanks released the docs deliberately, having to include some unflattering and damaging ones to look plausible, but with the primary aim of publicising Middle Eastern leaders' urging them to clobber Iranian nuclear facilities.

That way those leaders can't deny having urged them to do so, and even claim the opposite, if and when the US (or Israel) does attack the facilities, possibly with tactical underground nukes.

Sound plausible?
