Topic: 2026 – Clarification of Article 51
Country: Ukraine
Delegate Name: Shivani Salwi
As a founding member of the UN, the delegation of Ukraine remains committed to the principles of the UN Charter: to prevent wars and promote international peace. Article 51 of the UN Charter affirms the right of an individual’s self defense in response to an armed attack against a member State. Clarification of Article 51 has become increasingly important due to multiple threats such as state aggression and anticipatory self defense. Ukraine’s ongoing exposure with Russia’s ongoing unprovoked invasion displays the need to ensure that Article 51 serves as a protection for victims of aggression rather than a pretext.
The United Nations has taken efforts to address Article 51 but progress is still limited. States have also invoked Article 51 increasingly. In recent sessions, proposals such as those from Mexico and Brazil have sought to create forums for exchanging views on Article 51, with an increased focus on procedural transparency. The Council routinely receives notifications related to Article 51, but has given few resolutions, causing unchecked precedents to form. There is an absence of standardized requirements, as evidenced by the varied reporting formats.
The delegation of Ukraine asserts its right to self defense under Article 51 in response to Russia’s ongoing aggression since 2022. The defensive measures Ukraine has taken, including strikes on military targets to protect civilians comply with international law. Ukraine opposes broad pre-emptive strikes if a clear imminent threat is absent, insisting that self defense must be reactive to actual aggression. Ukraine openly welcomes collective self defense support from partners.
To strengthen Article 51’s implementation, Ukraine proposes that the Committee recommends clear guidelines that affirm that self defense is only permissible for an actual armed attack, while explicitly excluding pre-emptive actions that lack evidence. Reports to the Security Council should mandate standard content, which include details about the armed attack nature, timing as well as evidence to support the validity of the attack. The Committee should also initiate a review of post-2021 invocations in order to incorporate diverse perspectives to prevent unfair precedents that only support powerful states. Ukraine strongly believes that these steps would increase transparency, minimize abuse and overall boost commitment to collective security and peaceful settlement.
