Major International Conflicts

🟢 Lite — Quick Review (1h–1d)

Rapid summary for last-minute revision before your exam.

A major international conflict is an armed confrontation between states or between a state and an armed non-state actor that meets the intensity threshold for International Humanitarian Law (IHL) to apply. The LAT tests two legal axes: jus ad bellum (when force is lawful) and jus in bello (how force is conducted). Use of force is banned by Article 2(4) UN Charter, with two narrow exceptions: Article 51 self-defence (provisional, reportable to the UNSC) and Chapter VII UNSC authorisation. The UN Security Council is the only UN organ able to mandate coercive action; its decisions bind all members under Article 25.

  • IAC = state vs state (e.g., Russia–Ukraine, 2022–present).
  • NIAC = state vs non-state group, or group vs group (e.g., Sudan civil war, 2023–present).
  • IHL applies equally to both sides of any conflict, regardless of who started it.

Classifying a Conflict

The threshold test comes from the ICTY Appeals Chamber in Tadic (1995): intensity of violence plus organisation of armed groups determines whether a situation is an International Armed Conflict (IAC) under Common Article 2 Geneva Conventions or a Non-International Armed Conflict (NIAC) under Common Article 3. Classification matters because it dictates which treaty rules apply (the full Geneva Conventions for IACs, Common Article 3 + Additional Protocol II for NIACs).

Jus ad bellum answers whether force can be used. Article 2(4) prohibits it; Article 51 preserves the inherent right of self-defence until the UNSC acts. Jus in bello answers how force is used once a conflict exists, governed by the four Geneva Conventions 1949 and Additional Protocols 1977. Crucially, jus in bello applies to aggressor and victim alike.

UN Organs and Their Roles

OrganFunctionCharter basis
UN Security CouncilAuthorises coercive action, imposes sanctionsArticles 24, 25, 41, 42
UN General AssemblyDebates, recommends (e.g., Uniting for Peace)Articles 10–14
International Court of Justice (ICJ)Settles state disputes, advisory opinionsArticles 92, 36, 96
International Criminal Court (ICC)Prosecutes individuals for war crimes, genocideRome Statute (not UN Charter)

Neutral states, under Hague Conventions V and XIII (1907), must remain impartial and abstain from assisting any belligerent.

Edge Cases and Latent Traps

Cross-border hostilities between a state and an armed group based in another state blur IAC and NIAC labels — the Israel–Hamas/Hezbollah confrontations since October 2023 sit in this grey zone, with extraterritorial NIAC elements alongside classic IAC claims. LAT MCQs in many papers hinge on Article 51 limits: self-defence must be necessary, proportionate, and reported to the UNSC; pre-emptive strikes on non-imminent threats do not qualify.

Peacekeeping under Chapter VI is consent-based and lightly armed (force in self-defence only). Peace enforcement under Chapter VII is coercive and can include offensive operations (e.g., UNSC-authorised interventions in the Korean War, 1950; Libya, 2011). Confusing the two is the single most common LAT error on this topic.

Worked Application

Scenario: State A shells State B’s territory. State B retaliates without reporting to the UNSC.

  1. State A’s attack is a breach of Article 2(4) unless authorised by the UNSC.
  2. State B’s response can invoke Article 51 self-defence only if reported to the UNSC; failure to report renders the action unlawful under jus ad bellum.
  3. Once an IAC exists, both sides are bound by Geneva Conventions regardless of which fired first.

Common Mistakes

  • Treating UNGA resolutions as binding — they are recommendatory; only UNSC decisions bind under Article 25.
  • Confusing ICJ (state-to-state) with ICC (individual criminal responsibility).
  • Calling the Sudan civil war an IAC because foreign states are involved — it remains a NIAC unless foreign troops are integrated into party command structures.

Practice Prompts

  1. Identify the IAC/NIAC status of the Russia–Ukraine war since 2022 and cite the Geneva provision that governs POW treatment.
  2. A state invokes Article 51 after a cyber-attack on its power grid. Evaluate the lawfulness under current ICJ jurisprudence (Nicaragua v. USA, 1986; Armed Activities in the Congo, 2005).
