That pic is from the Cuban missile crisis.
Perhaps the black and white photos from that time were what Scavino wanted to bring to mind. I think there is one with Kennedy on the phone.
(Something going on out there beyond the trees.)
So yes, closed door call, about National Security.... decisions of a warlike setting.
All I can say is DUH...yes, it appears to anyone paying attention that we are in a scenario not just as dire as Cuban Missile crisis, but potentially far worse. Worse because much of our nation is in on the plot against us!
