Not much info there to have humint assets, you're right. (I doubt we need agricultural trade secrets from them.)
I'll bet the electromagnetic spectrum is lit up with communications right now. Just the logistics of deploying 50,000 troops/specialists is a major task.
I would think that we'd have JSTARS up on the move and/or satellites in position to monitor this one.
The silence of the MSM is typical. (Sleep, sheep.)
I have only registered all this lately and usually I am the first to sneer at millenarian alarmism but this scares the sh*t out of me.
