Introduction
The contemporary landscape of international relations is marked by several protracted conflicts that challenge the foundational principles of international law, particularly those governing the use of force by states (jus ad bellum) and the conduct during armed conflicts (jus in bello). This essay examines the ongoing disputes between Russia and Ukraine, the tensions involving the USA and Israel with Iran, and the border skirmishes between Pakistan and Afghanistan. Drawing on key legal authorities such as the United Nations Charter and the Geneva Conventions, it identifies critical issues related to the prohibition on the use of force, self-defence exceptions, and humanitarian protections in warfare. Through examples from these conflicts, the essay argues that while international law provides mechanisms to resolve such issues—such as through the International Court of Justice (ICJ) or accountability via international tribunals—enforcement remains inconsistent due to geopolitical realities. The discussion will proceed by analysing jus ad bellum concerns, followed by jus in bello violations, before concluding with implications for global order. This approach reflects a student’s perspective in international law studies, emphasising the tension between legal norms and state practice.
Use of Force: Prohibition and Exceptions under International Law
International law strictly regulates the use of force to maintain peace and security, as enshrined in Article 2(4) of the UN Charter, which prohibits “the threat or use of force against the territorial integrity or political independence of any state” (United Nations, 1945). However, Article 51 allows for self-defence in response to an armed attack, providing a key exception. These provisions raise significant issues in the selected conflicts, where states often justify actions under self-defence claims, yet interpretations vary, leading to disputes over legality.
In the Russia-Ukraine conflict, Russia’s full-scale invasion in February 2022 exemplifies a clear violation of the prohibition on force. Russia annexed Crimea in 2014 and later territories in eastern Ukraine, actions condemned by the UN General Assembly as breaches of Ukraine’s sovereignty (United Nations General Assembly, 2022). Russia invoked Article 51, claiming pre-emptive self-defence against alleged NATO threats and genocide in Donbas, but this lacks substantiation. The ICJ, in its advisory opinions and cases like Military and Paramilitary Activities in and against Nicaragua (Nicaragua v. United States), has clarified that self-defence must respond to an actual armed attack, not speculative threats (International Court of Justice, 1986). Thus, Russia’s actions arguably constitute aggression under UN Resolution 3314, which defines aggression as invasion or bombardment (United Nations General Assembly, 1974). Resolution could involve ICJ adjudication or sanctions, though Russia’s veto power in the Security Council hinders enforcement.
Similarly, tensions between the USA/Israel and Iran involve proxy conflicts and targeted strikes that test the boundaries of self-defence. For instance, the USA’s drone strike killing Iranian General Qasem Soleimani in January 2020 was justified as self-defence against imminent threats to US personnel in Iraq (White House, 2020). Israel has conducted airstrikes on Iranian-linked targets in Syria, claiming prevention of attacks on its territory. These actions align with a broader interpretation of anticipatory self-defence, as discussed in legal scholarship, where force is permissible if an attack is imminent (Shaw, 2017). However, critics argue this stretches Article 51, potentially eroding the prohibition on force. The Caroline incident (1837) sets a precedent for necessity and proportionality in self-defence, requiring that the threat be “instant, overwhelming, leaving no choice of means” (Jennings and Watts, 1992). In this context, resolving the issue might require referral to the ICJ for clarification, though states like the USA often bypass such mechanisms, relying instead on bilateral diplomacy or UN Security Council resolutions.
The Pakistan-Afghanistan border conflict further illustrates these issues, with frequent cross-border incidents involving Taliban forces and Pakistani military responses. Pakistan has conducted airstrikes into Afghanistan, citing self-defence against terrorist safe havens, such as those harbouring the Tehrik-i-Taliban Pakistan (TTP) (Human Rights Watch, 2023). This echoes self-defence claims but raises questions of proportionality, as civilian casualties have been reported. International law, per the ICJ’s Wall advisory opinion, emphasises that self-defence must not infringe on occupied territories’ rights, though Afghanistan is not occupied (International Court of Justice, 2004). To resolve this, enhanced bilateral agreements or mediation through the UN could enforce compliance with Article 2(4), preventing escalation.
Overall, these examples highlight how self-defence is often invoked to justify force, yet legal authority demands strict adherence to necessity and proportionality. A critical approach reveals limitations: powerful states manipulate interpretations, underscoring the need for stronger ICJ enforcement.
Conduct of Armed Conflict: Humanitarian Law Violations
Beyond the initiation of force, international humanitarian law (IHL), primarily the Geneva Conventions of 1949 and their Additional Protocols, governs conduct in armed conflicts, mandating distinction between combatants and civilians, proportionality, and prohibition of unnecessary suffering (International Committee of the Red Cross, 1949). Violations in the discussed conflicts raise issues of accountability and the applicability of IHL to non-international armed conflicts.
In Russia-Ukraine, reports of indiscriminate bombings in civilian areas, such as Mariupol in 2022, violate Common Article 3 of the Geneva Conventions, which applies to non-international conflicts and prohibits violence to life and person (Human Rights Watch, 2022). Russia’s alleged use of cluster munitions exemplifies breaches of proportionality, as these weapons cause widespread harm. The International Criminal Court (ICC) has issued arrest warrants for Russian officials, invoking Rome Statute provisions on war crimes (International Criminal Court, 2023). Resolution here involves ICC prosecutions, though Russia’s non-membership limits effectiveness; alternatively, universal jurisdiction allows national courts to pursue cases.
In the USA/Israel-Iran dynamic, drone strikes and proxy warfare often blur lines between international and non-international conflicts. Israel’s operations against Iranian-backed Hezbollah in Lebanon have led to civilian casualties, potentially violating Additional Protocol I’s requirement for precautionary measures (Amnesty International, 2021). The USA’s strikes in Iraq against Iranian militias similarly risk disproportionate harm. Legal authority from the ICJ’s Nuclear Weapons advisory opinion stresses that IHL applies universally, prohibiting actions causing superfluous injury (International Court of Justice, 1996). Addressing this could involve UN Human Rights Council investigations, fostering compliance through reporting and sanctions.
Pakistan-Afghanistan conflicts feature allegations of IHL breaches, including Pakistani forces’ reported targeting of Afghan civilians during border operations (United Nations Assistance Mission in Afghanistan, 2022). This contravenes the principle of distinction. As a non-international conflict involving the Taliban, Common Article 3 applies, demanding humane treatment. Resolution might entail International Committee of the Red Cross (ICRC) mediation or adherence to the Kampala Convention on internally displaced persons, though enforcement is challenged by state sovereignty.
These cases demonstrate IHL’s relevance but also its limitations in asymmetric conflicts, where non-state actors complicate accountability. A logical evaluation suggests that strengthening hybrid tribunals could bridge gaps.
Conclusion
In summary, the conflicts between Russia and Ukraine, USA/Israel and Iran, and Pakistan and Afghanistan underscore critical international law issues: violations of the UN Charter’s prohibition on force, expansive self-defence claims, and breaches of IHL principles like distinction and proportionality. Legal authorities such as the UN Charter, Geneva Conventions, and ICJ precedents provide frameworks for resolution through adjudication, sanctions, and prosecutions. However, geopolitical influences often impede enforcement, revealing the limitations of international law in practice. For global stability, states must prioritise compliance, perhaps through reformed UN mechanisms. This analysis, from a law student’s viewpoint, highlights the field’s evolving nature, where theoretical norms meet real-world challenges, urging further research into enforcement strategies. Ultimately, addressing these issues is essential to prevent escalation and uphold the rule of law.
