Having spent time deployed, I think a lot of Americans might be conditioned to seeing immediate(ish) responses to threats via Drones, SEAL team 6, Ranger Regiment, whatever. The nature, and future, of Cyberwar is something that's fundamentally different from what we've seen broadcast on CNN over the last 13 (soon to be 14...15...) years. A response to North Korea (though I'm not truly convinced that they're the lone perpetrators) might not be something that pops up in The Situation Room with Wolf Blitzer or trends on Twitter.
