The Pentagon's principal cyber advisor, Assistant Secretary of Defense Eric Rosenbach, said about cyber operations last month, "The place where I think it will be most helpful to senior policymakers is what I call in 'the space between'. What is the space between? ... You have diplomacy, economic sanctions...and then you have military action. In between there's this space, right? In cyber, there are a lot of things that you can do in that space between that can help us accomplish the national interest."
