National actors believe they have a real interest in trying to shape discussions in other cyberspaces, witness China and Twitter as well as the White House’s announcement this week that it was issuing guidances that would make it easier to transfer software and services that “support the free flow of information to citizens of Iran.”

This point shades over into my last. We have a tendency to talk about the cyber problem in U.S.-China relations—cyberwar and cyberespionage. But this week reminds us that what we are often also talking about is really a conflict over information. Cyber is just the means.
