This looks like it came from someone who had access to State and military docs. The person would have to be very high up to do this. I suspect that there are several people involved.
It is also possible that they have been sending like docs to others whom we do not wish to have these docs.
This is disastrous.
“This is disastrous.”
Maybe not. Maybe Assange has done the Amercian public a favor. And if he could get this stuff, then either it is not of much value to our real enemies, or it is already known to them.
