Have you heard of the “pre-emptive cyber strike” doctrine?

I view “preemptive cyber strike” as the digital counterpart to the Bush-era pre-emptive strike doctrine expressed in a national security policy document in September 2002. This policy  was used to “justify” U.S. actions in Afghanistan and Iraq:

To forestall or prevent such hostile acts by our adversaries, the United States will, if necessary, act preemptively in exercising our inherent right of self-defense. The United States will not resort to force in all cases to preempt emerging threats. Our preference is that nonmilitary actions succeed. And no country should ever use preemption as a pretext for aggression.

While contemplating the implications of preemptive cyber strike for critical infrastructure, I had this novel idea for a NERC CIP-005 R2-“compliant” appropriate use banner:
