Exercising self-defence is a nation's primary right when a situation demands "immediate and proportionate action" and applies also to attacks by non-state actors, India told a UN meeting, highlighting several proxy cross-border and state-supported terrorist attacks like the 26/11 Mumbai assault the country was subjected to from its neighbour.
India's Deputy Permanent Representative to the UN Ambassador K Nagaraj Naidu said at an Arria Formula meeting organised by Mexico that a 1974 UN General Assembly declaration requires that a member state should not allow territory under its control to be used for terrorism against another state.
The Arria Formula meetings are informal meetings on Upholding the collective security system of the UN Charter: the use of force in international law, non-state actors and legitimate self-defence'.
The Security Council also mandates all states to refrain from providing any form of support, active or passive, to entities or persons involved in terrorist acts, Naidu said on Wednesday.
Despite this, some states are resorting to proxy war by supporting non-state actors such as terrorist groups to evade international censure. Such support to non-state actors has ranged from providing and equipping the terrorist groups with training, financing, intelligence and weapons to logistics and recruitment facilitation, he said.
India for decades has been subject to such proxy cross-border and relentless state-supported terrorist attacks from our neighbourhood, he said.
"Whether it is was the 1993 Mumbai bombings, or the random and indiscriminate firings of 26/11 which witnessed the launch of the phenomenon of lone-wolves or more recently, the cowardly attacks in Pathankot and Pulwama, the world has been witness to the fact that India has repeatedly been targeted by such non-state actors with the active complicity of another host State, Naidu said.
Naidu told the meeting that exercising self-defence is a primary right of States to be exercised when the situation is imminent and demands necessary, immediate, and proportionate action and that customary international law has long recognised the principles governing the use of force in self-defence.
He noted that Article 51 of the UN Charter is not confined to self-defence in response to attacks by states only.
"The right of self-defence applies also to attacks by non-state actors. In fact, the source of the attack, whether a state or a non-state actor, is irrelevant to the existence of the right of self-defence.
Naidu stressed that India believes that instances where states have exercised the right of self-defence to attack non-state actors located in other states must be consistent with Article 2(4) of the UN Charter.
Preemptive actions taken to fight the menace of terrorism, even without the consent of the state hosting the non-state actors, meets this criterion because such actions are not of reprisal since their prime motive is for protecting the affected states' national integrity and sovereignty, he said.
Article 2(4) of the UN Charter states that all Members shall refrain in their international relations from the threat or use of force against the territorial integrity or political independence of any state, or in any other manner inconsistent with the Purposes of the United Nations.
Naidu told the meeting that non-state actors such as terrorist groups often attack states from remote locations within other host states, using the sovereignty of that host state as a smokescreen.
On this, a growing number of states believe that the use of force in self-defence against a non-state actor operating in the territory of another host state can be undertaken if the non-state actor has repeatedly undertaken armed attacks against the state, the host state is unwilling to address the threat posed by the non-state actor and is actively supporting and sponsoring the attack by the non-state actor.
In other words, a state would be compelled to undertake a pre-emptive strike when it is confronted by an imminent armed attack from a non-state actor operating in a third state, Naidu said.
He added that these circumstances exonerate the affected state from the duty to respect, vis-a-vis the aggressor, the general obligation to refrain from the use of force.
"In fact, Security Council resolutions 1368 (2001) and 1373 (2001) have formally endorsed the view that self-defence is available to avert terrorist attacks such as in the case of the 9/11 attacks," he added.
Noting that Article 2(4) of the UN Charter requires that states refrain from the use of force, he said the drafting history of Article 51 of the UN Charter and the relevant San Francisco Conference Report of June 1945 that considered Article 2(4) of the UN Charter mentions that the use of arms in legitimate self-defence remains admitted and unimpaired.
He added that Article 51 also explicitly acknowledges the pre-existing customary right of self-defence, as recognised by the International Court of Justice and the UN Security Council by stating that nothing in the present Charter shall impair the inherent right of individual or collective self-defence.
