"You've got to stop this war in Afghanistan."
"Patient zero" seems to be this Twitter feed.
I'm a great admirer of Richard Holbrooke and I share the widely held view that we've lost a giant. But were these his "last words?" I doubt it. I think it is pretty clear by now that "last words" are a cultural construct, especially popular in Victorian times though I bet they go back to the stoics (cf. "see how a Christian dies!"). The reality is virtually always less theatrical.
But here's a guess: it wouldn't knock me over to find out that Holbrooke, hospitalized, in extremis and with his loved ones, indulged in a moment of black humor to say "yeh, if I go, tell them my last words were..." This guy was as dedicated, determined--and savvy--as any diplomat whose services we ever enjoyed. And he understood that part of the job was playing the media.
OBTW, whether or not I am right, let's agree that he was right.
