Apparently, when greeting a French person, an American style bear hug is not desired. Instead, it's the peck on the cheek. Shockingly ( or not) Kerry grabbed up the much shorter Hollande and hugged away. You can see the disgust on Hollande's face below. Not liking it.
I won't even comment on the idea that bringing James Taylor to serenade the French is a good one. They are very serious and intellectual, those State Department geniuses.
Hollande is thinking, "Keep your distance, Americaine!! And let go of my hand!"
