This picture says it all. The Vice President seated at the table wearing office attire. The Secretary of State seated at the table wearing office attire. Everyone in the room is wearing office attire. Everyone except the President. The President who is wearing his golf clothes. The President who has no seat at the table. The President with the scowl on his face because he was dragged off the golf course so that they could have this photo shoot.
I am thoroughly convinced that someone else gave the kill order and that Obama had nothing to do with it. Which is why the glum look.
If this had been Trump or Bush, either would be showing some intense expression of glee, satisfaction, or relief. But not Obama. He doesn't look at all like he wants to be there.
Look at Hillary (hand over mouth--How often do you see that?) and Biden, too. They look more like this is a disaster, not a cause for celebration. Also, of all the objects and people in the image, the top sheet laying on Hillary's laptop is heavily pixelated if you enlarge the image (not the one blow it, just the top one), fwiw.
