Could he look sadder? I mean more than usual.
He's still only in Baghdad:
US Secretary of State John Kerry held talks with Iraq's new leaders Wednesday on their role in a long-awaited strategy against Islamic State jihadists to be unveiled by President Barack Obama.
Kerry wanted a mission. And for his sins President Obama gave him one.
It's Kerry's own fault, of course. He should have studied harder.
