We reject techniques like torture regardless of whether they're effective or ineffective because they are barbaric and harmful on a broad scale. It's the same thing with cyber warfare. We should never be attacking hospitals. We should never be taking down power plants unless that is absolutely necessary to ensure our continued existence as a free people.

We have a media that goes along with the government by parroting phrases intended to provoke a certain emotional response - for example, "national security." Everyone says "national security" to the point that we now must use the term "national security." But it is not national security that they're concerned with; it is state security. And that's a key distinction.

If an adversary didn't target our power plants but they did target the core routers, the backbones that tie our internet connections together, entire parts of the United States could be cut off. That would have a tremendous impact on us as a society and it would have a policy backlash.

It's important to remember when you start doing things like attacking hospitals through the internet, when you start attacking things like internet exchange points, when something goes wrong, people can die. If a hospital's infrastructure is affected, lifesaving equipment turns off.

When it comes to cyber conflicts between, say, America and China or even a Middle Eastern nation, an African nation, a Latin American nation, a European nation, we have more to lose.

The only thing I fear is the harmful effects on my family, who I won't be able to help any more. That's what keeps me up at night.

What I wanted to do was give society the information it needed to decide if it wanted to change the system.
