"I for one am not happy about the anarchy of the internet."
Fair enough. I'm not happy about the anarchy wrought in Iraq following the invasion; and I'm equally unhappy about the anarchy of deranged scum flying planes into towers or blowing-up underground trains. But, hey, your unhappiness is as valid as everyone else's so let's just shut down the internet.
"When someone post a video of a kidnapped contract worker being beheaded, we should be able to locate the origin of that post and get the people who did it."

As to the term 'war czar', it strikes me as a fitting epitaph for the departing Blair.
