Topic: 2026 – Clarification of Article 51
Country: Nigeria
Delegate Name: Aiden Lin
Nigeria itself has never had the need to invoke Article 51 of the UN Charter, although it has needed to defend itself from armed groups, such as Boko Haram. These groups are a danger to Nigeria’s population, land, and economy. They have carried out attacks that have killed both civilians and government forces with a death count of around 40,000 people, and damaged the land through their suicide bombing.
Nigeria, under Article 51, believes that self-defense can only be invoked when there is an immediate threat to a country’s sovereignty. Countries must not rely on speculation and pre-emptive strikes because it doesn’t constitute self-defense. If a country does use self-defense, the force used must be equal to the force used against them. In addition, the defending country must not have caused the conflict with its words or behavior. Both the defending and aggressing countries should aim to keep civilian involvement and casualties to a minimum as well.
When a country tries to implement Article 51, Nigeria believes that they should submit a report to the United Nations stating what the attack targeted, its duration, the severity of it. It then should be reviewed by the United Nations to decide if the country’s use of Article 51 is legitimate. The country may defend itself immediately, but once the threat is over, they should send a report to the UN stating what measures they took and why. In addition to reviewing reports, in order to maintain international peace, the UN should adopt a restrictive interpretation of the meaning of self-defense, only allowing it in actual armed attacks to preserve state sovereignty. Nigeria also wishes to recognize the threat of cyber attacks on a country’s security and economy. They are comparable in damage to an armed attack and should justify a country’s use of Article 51 in a case of a cyber attack, reinforcing the importance of minimizing damage to civilians and infrastructure.
In order to better implement Article 51 of the UN Charter, Nigeria strongly advocates for improved oversight regarding countries’ use of it. By establishing clearer guidelines for what can be classified as a dangerous attack-anything that threatens state sovereignty, whether armed or cyber, it will lower the usage of Article 51 and prevent its misuse. When a country does use Article 51, after the threat is over, they must send a report to the UN charter stating the measures they took and the reasons behind it. The UN should also cooperate with regional organizations such as the AU or the EU when deciding. These organizations have a deeper understanding and involvement with the conflicts occurring in their respective regions. These views come from Nigeria’s past of being a British colony. Britain used Nigeria as a place for natural resources, disregarding its various ethnic groups and economic autonomy resulting in Nigeria’s view of self sovereignty.
