The character of warfare is evolving and China and Russia are constantly interpreting international rules in a way that threatens “the ethical and legal basis on which we apply armed conflict.” With the new domain of cyberspace, warfare is ongoing and more sophisticated, and the only way to obtain an edge is to have the most information. Carter describes the difficulty in maintaining credible military deterrence while also preparing troops for cyber warfare. While nations tread further into the world of cyber warfare, the line between what constitutes as war and what does not is blurring. Britain, a middleweight power, struggled to understand which situations justify their use of diverting resources. Carter believes that Britain is already in a state of war, and that the time is now to start defending.
