Since 1990 the international security law has undergone deep changes. As an example, the use of force by states against non-state actors have most frequently involved the neighboring or third states. These situations pose several questions about the legitimacy of such reactions endangering the sovereignty of other states. Victim states using force justify their actions in the name of self-defense. In practice, we consider less opposition by the international community as well as the ICJ in order to treat these measures illegal. Considering the doctrine, we observe a real divergence among famous scholars. By noting several cases before the international tribunals, in particular in ICJ we try to analyze the legality and legitimacy of the use of force by aggressor states against the territorial integrity of others under the existing rules of international law.
