Beres, Louis René. “Defending Israel against Iranian Nuclear Aggression: War, Genocide, and International Law.” Israel Journal of Foreign Affairs (early view; online first).
Under authoritative international law, aggressive war and genocide need not be mutually exclusive. On the contrary, war can intentionally create the conditions that would make genocide possible; it can also be the more direct or immediate instrument of closely related crimes against humanity. It follows then, as Iran comes ever closer to achieving a viable nuclear weapons capability, that Israel has an especially good reason to fear future conflicts with such an aggression-prone Islamic republic.
Ultimately, any war launched by Iran could become genocidal.
