Article 51 of the UN Charter and Self Defense


The language of this article is restrictive: "Nothing in the present Charter shall impair the inherent right of individual or collective self-defense if an armed attack occurs against a member of the United Nations, until the Security Council has taken measures to maintain international peace and security." However, a threatened State, according to long established international law, can take military action as long as the threatened attack is imminent, no other means would deflect it and the action is proportionate. The problem arises where the threat in question is not imminent but still claimed to be real: for example the acquisition, with allegedly hostile intent, of nuclear weapons-making capability.

Can a State, without going to the Security Council, claim in these circumstances the right to act, in anticipatory self-defense, not just pre-emptively (against an imminent or proximate threat) but preventively (against a non-imminent or non-proximate one)? Those who say "yes" argue that the potential harm from some threats (e.g. terrorists armed with a nuclear weapon) is so great that one simply cannot risk waiting until they become imminent, and that less harm may be done (e.g. avoiding a nuclear exchange or radioactive fallout from a reactor destruction) by acting earlier.

The short answer is that if there are good arguments for preventive military action, with good evidence to support them, they should be put to the Security Council, which can authorize such action if it chooses to. If it does not so choose, there will be, by definition, time to pursue other strategies, including persuasion, negotiation, deterrence and containment -- and to visit again the military option.

For those impatient with such a response, the answer must be that, in a world full of perceived potential threats, the risk to the global order and the norm of non-intervention on which it continues to be based is simply too great for the legality of unilateral preventive action, as distinct from collectively endorsed action, to be accepted. Allowing one to so act is to allow all.

We do not favour the rewriting or reinterpretation of Article 51.
