Cyberwarfare not directed at or effectuating physical destruction of materiel and/or persons is merely metaphorical rather than actual warfare, or is part of the information component of a broader war. (OTOH, cyberwarfare can be, in fact, a direct means of achieving physical destruction of materiel and/or persons.)
