In land, sea, and air battles, military combatants can see the enemy coming, whether it's the whites of their eyes or a blip on a screen. International boundaries easily define when an aggressor threatens the sovereignty of a nation, giving the victim nation the right of jurisdiction, and there are specific international laws that address military operations in space. In addition, the international community has defined when an adversary's use of force threatens a nation's territorial integrity and political independence. However, the global nature of cyberspace and the speed of which victims can experience cyber attacks force nations to deal with the legal challenges associated with over-the-horizon military operations.
