But political tensions and the conflict in Syria took center stage at this year’s gathering, which was hosted by Russia. With the world watching, Vladimir Putin, David Cameron, Barack Obama, François Hollande and other heads of state put on their best poker faces.

But this time he held back, unwittingly signaling the deep political rift between the U.S. and Russia.

Just kidding, he didn't say anything of the sort. In fact, given how well these two get along, we can only assume he reciprocated the platonic squeeze.
