Picture on the right: agreed, and unusual. Pic on the left, not so much. I guess the danger is the "little green men" strategy that Russia used in Ukraine / Crimea. If people have to travel in and out, the ID checks will be useful. If they rush the White House, the fencing to lock them in seems appropriate. I had thought of troops being invited in, not troops sprouting up from within, but it's plausible. And makes the mobilized numbers more sensible. I guess. Something to consider.
