He's writing a terse letter to the Israeli's for provoking their blood-thirsty enemies into firing missiles at Israeli schoolchildren and civilians.
Probable content of said letter:
Dear Bibi:
This is what happens when you obstruct the piece process. Surrender to these people, and they won’t hurt you too bad, and you may even get to stay Prime Minister of whatever’s left of the Zionist Entity. I need a photo op handshake between you and Abbas, and a drop in oil prices by October. You’re the one to give it to me. Now get busy.
Oh, and sorry ‘bout those missiles. This senseless violence will not stop the piece process. Right? Right.
I remain, sir, as ever, your worst nightmare,
Sincerely,
Barack Hussein Obama
President of the United States
