One of my favorite photos of all time comes from a 2012 March Madness basketball game that then-president Barack Obama attended with then-British prime minister David Cameron. The picture captures the two men perfectly. It shows Obama sitting courtside with a hot dog in his hand pointing and lecturing in that quintessential Obama way, while Cameron glowers and appears to contemplate all the places he’d rather be — getting an endoscopy, bombing Libya, anywhere else on the planet, really.
