Steven Aftergood, Secrecy News: “What constitutes an act of war in the cyber domain? It’s a question that officials have wrestled with for some time without being able to provide a clear-cut answer. But in newly-published responses to questions from the Senate Armed Services Committee, the Pentagon ventured last year that “The determination of what constitutes an ‘act of war’ in or out of cyberspace, would be made on a case-by-case and fact-specific basis by the President.” “Specifically,” wrote then-Undersecretary of Defense (Intelligence) Marcel Lettre, “cyber attacks that proximately result in a significant loss of life, injury, destruction of critical infrastructure, or serious economic impact should be closely assessed as to whether or not they would be considered an unlawful attack or an ‘act of war.'” Notably absent from this description is election-tampering or information operations designed to disrupt the electoral process or manipulate public discourse. Accordingly, Mr. Lettre declared last year that “As of this point, we have not assessed that any particular cyber activity [against] us has constituted an act of war.”
