Cause for thought: Israel’s airstrikes directed against Iran and Syria
Israel has acknowledged to have repeatedly struck Iranian military targets in Syria. While confrontations occur frequently, the incident of January 21, 2019 has received particular attention. Israeli guided missiles, apparently fired over Lebanese territory (UN Doc. S/PV.8449, p. 31f), hit Iranian military targets in Syria, also leading to personal and material damage of Syria. Israel invoked its right to self-defense, apparently reacting to Iran firing a surface-to-surface missile towards the Golan Heights on Sunday, January 20 from Syrian territory. Syria’s precise role in the Iranian action beyond this territorial link remains murky.
The problem: self-defense affecting assisting states
The Israeli claim to self-defense faces various legal questions (e.g. whether the attack meets the necessary threshold or whether annexed territories can be defended). This contribution does not aim to assess the Israeli claim, but shall use this example to shed light on one problem only: May the victim of an armed attack defend itself not only against the attacker state, but also against an “assisting” state?
Even if the use of force by the defending state (here Israel) against the attacking state (here Iran) is assumed to be justified by self-defense, it also forcefully infringes upon the territorial integrity of the assisting State (here Syria), as protected under Article 2(4) UNC, and warrants justification, too. The claim that strikes directed against an actor within the territory of another state are not a prohibited use of force against the territorial state has been repeatedly rebutted.
In fact, in the Security Council debate on the January incident, Syria labelled the Israeli strikes as “acts of aggression targeting the Syrian Arab Republic”, a “gross violation of international law” (S/PV.8449, p. 31f). Iran like Russia condemned the Israeli action, emphasizing the infringement of Syria’s sovereignty. Interestingly, Israel (unlike the USA or Germany) showed awareness of the problem by holding “the Syrian regime responsible for the missile that was launched against Israel from Syrian territory” (S/PV.8449, p. 8). The IDF added that “Syria paid the price for allowing Iran to conduct attacks from its soil.”
While the permissibility of self-defense against states supporting non-state actor violence is being extensively discussed, self-defense against states assisting another state has received little attention Read the rest of this entry…
