The United States, however, takes an outlier position, consistently arguing that any illegal use of force gives rise to the use of force in self-defence.[2] In Nicaragua, the ICJ identified “scale and effects” as criteria upon which to judge whether a use of force constitutes an armed attack. In the Court’s view, only “the most grave” uses of force do so.[3] Thus, only cyber operations that seriously injure or kill a number of persons or cause significant damage to, or destruction of, property would undoubtedly constitute armed attacks.[4] |
