Trump does not look in good health. He's put on more weight. He can't stay awake and isn't mobile.

7. dunno if he was napping or just sulking in that pose

and in the pic from the Nato meeting.
The impression I got from the pics is that he was pouting. He does not like to share limelight,
and in the Brussels meeting he was just one of many.

What he does is all the attention grabbing behaviors, like what he did during the debate with Hillary,
pacing around the stage, interrupting, making faces.
I viewed one of his depositions, where he did the same thing when forced to sit thru the session which
he had no control over..he wiggled, lots of body movement, made faces and loudly turned pages and tried joking.

I did notice at the Nato meeting, Merkel was markedly noticing his lack of headphones, closed eyes.
So his attention seeking behavior worked for a bit.
He is incapable of being just a member of a group. It has to be all him or nothing else, even if he has to assault someone to get in the front row of cameras.
