"And this President doing so, with what looked like admirable ease, on a night like that now looks, in retrospect, like alarmingly accomplished cool. His pulse was low, his timing sound, his laughter deep; his extremely adept zinging of the Donald made all the papers and video blogs, of course, but what was perhaps less visible outside the hall was how delightedly relaxed he seemed as Seth Meyers zinged him. Trump’s head was locked in place, a varnished fixture, like the figurehead on the prow of a sailing ship at a pirate ride; Obama laughed and ducked and shook his (surprisingly whitened) hair with pleasure. And now we know, all the while, he knew that the very chancy order he had already given could very well spell the end of his Presidency. (And let us not lose sight of the reality that it nearly did all go wrong; that helicopter going down is a touch the screenwriter would have been reluctant to add on his own.)
Doubtless any President would have managed to more or less pull through—Presidents get to be Presidents by not showing much stress under pressure, save Richard Nixon, who showed enough for all the rest of them together—but this was super-cool, blood cool, true cool."
