You and I have discussed this.
I don’t think there is any one in government who knows more about this subject than President Trump.
Any “briefing” would be just a waste of his time.
The issue is not what he knows—it is whether he wants anyone else to know.
Yes. I see your point.
As Chris Mellon has said, the DOD is so stovepiped that some of what is going on never gets to the top and is never shared with anyone outside the few that know.
Then on the other hand, as you have said, there is hidden shadow government (perhaps even another world) wherein many people are involved.
I'm not sure what to believe about all this.
