Applying International Law to Resistance and Irregular Combatants

The Resistance Hub

The rules of armed conflict—commonly referred to as international humanitarian law (IHL)—aim to balance military necessity with humanitarian considerations. These rules apply to state and non-state actors, including resistance movements and irregular combatants. However, interpreting and applying these principles in the context of modern conflicts remains complex and contentious. This article explores the application of international law to resistance and irregular combatants, addresses human rights concerns, and highlights relevant historical and contemporary examples, including Russia’s actions in Ukraine.

Defining Key Terms and Principles

Combatants, Non-Combatants, and Protected Classes

Under IHL, individuals in conflict are categorized into specific statuses:

1. Combatants: Members of armed forces or groups directly participating in hostilities. Combatants have the right to engage in attacks against legitimate military targets and, if captured, are entitled to prisoner-of-war (POW) status.
2. Non-Combatants: Civilians not directly participating in hostilities. They are protected under IHL and cannot be targeted.
3. Protected Classes: Includes medical personnel, humanitarian workers, and religious officials. These individuals must be safeguarded during conflicts. The deliberate targeting or endangerment of protected classes constitutes a severe violation of IHL and may lead to war crimes investigations.

Valid Military Targets

A valid military target is defined under Article 52 of Additional Protocol I to the Geneva Conventions as an object that contributes effectively to military action and offers a definite military advantage when destroyed, neutralized, or captured. Examples include:

• Weapons stockpiles
• Communication centers
• Military command facilities

However, civilian objects such as schools, hospitals, and residential areas are generally protected unless used for military purposes.

Dual-Use Infrastructure

Dual-use infrastructure presents significant challenges in modern warfare. While certain civilian objects may serve both civilian and military purposes, IHL strictly limits their targeting to cases where military necessity outweighs civilian harm. Examples of dual-use infrastructure include:

• Bridges and Roads: Permissible targets only if they are actively used for military operations.
• Telecommunication Networks: Targetable if they provide command and control functions for military forces.
• Energy Facilities: Power plants serving both civilian and military needs can only be targeted when essential to disrupting military capabilities.

However, specific civilian dual-use infrastructure is prohibited from sabotage, including:

• Water treatment facilities critical to civilian populations
• Hospitals, even if temporarily used by military forces
• Religious and cultural sites, unless converted into operational military facilities

Targeting any of these objects can have devastating consequences for civilian populations, often leading to humanitarian crises.

Resistance and Irregular Combatants: Legal Considerations

Legal Status of Resistance Fighters

Resistance movements often involve non-state actors or irregular combatants, who may lack formal uniforms and hierarchical structures. The Geneva Conventions recognize resistance fighters as lawful combatants if they meet certain conditions, including:

• Carrying arms openly during military operations
• Operating under a responsible command
• Distinguishing themselves from civilians to the extent feasible

Failure to adhere to these conditions may classify resistance fighters as unlawful combatants, exposing them to prosecution under domestic laws. In practice, achieving and maintaining these conditions during resistance efforts can be extraordinarily difficult, particularly under occupation or asymmetrical warfare scenarios.

Civilian Attire and Resistance

International law allows irregular combatants to operate in civilian attire under limited circumstances, particularly in occupied territories. However, the principle of distinction remains critical—fighters must distinguish themselves during attacks to avoid endangering civilian populations. Historical examples include the French Resistance during World War II, whose members faced legal and ethical challenges in adhering to these standards. Failure to maintain a clear distinction can result in severe repercussions, including reprisals against civilian populations.

Human Rights and Collateral Damage

Balancing Military Necessity and Ethical Obligations

The concept of proportionality prohibits attacks expected to cause excessive civilian harm to the anticipated military advantage. This principle seeks to minimize collateral damage while acknowledging the realities of war. Commanders are required to carefully weigh the military benefits of an operation against the potential for civilian harm. Targeting decisions must also consider precautions, such as warning civilians before attacks when feasible.

Contemporary Challenges

Modern conflicts often blur the lines between combatants and civilians, particularly in urban warfare. For example:

• The use of human shields by combatants complicates targeting decisions and raises profound ethical and legal concerns.
• Dual-use infrastructure, such as bridges and factories, challenges the distinction between civilian and military objects.
• Prolonged sieges often strain the principle of proportionality, as essential civilian supplies like food and medicine are interrupted.

Legal Mechanisms for Accountability

Enforcement of IHL

International mechanisms play a vital role in enforcing IHL. The International Criminal Court (ICC) and ad hoc tribunals investigate and prosecute war crimes, crimes against humanity, and genocide. However, holding irregular combatants accountable often presents additional challenges due to jurisdictional and evidentiary issues. States are also obligated under IHL to prosecute war crimes committed within their jurisdiction or to cooperate with international bodies.

Current Investigations

Ongoing investigations into Russia’s actions in Ukraine, including alleged war crimes and crimes against humanity, demonstrate the international community’s commitment to accountability. The establishment of evidence-collection mechanisms and trials underscores this effort. For instance, the deliberate targeting of civilian shelters, documented through satellite imagery and eyewitness accounts, has led to preliminary findings of violations of IHL.

Modern Warfare Trends

Cyber Warfare

IHL principles increasingly apply to non-physical forms of combat, including cyberattacks. Cyber operations targeting critical infrastructure—such as hospitals or water systems—must comply with proportionality and distinction principles. The use of malware to disable essential civilian services is widely condemned and may constitute a violation of IHL.

Drones and Autonomous Weapons

The use of drones and autonomous weapons introduces new complexities. These technologies raise ethical questions regarding accountability and proportionality in targeting. Autonomous weapons, in particular, present challenges in ensuring compliance with IHL principles due to potential gaps in human oversight.

Hybrid Warfare

Hybrid tactics, blending military and civilian domains (e.g., misinformation, sabotage), challenge the application of IHL and blur traditional combatant distinctions. Such tactics often exacerbate civilian suffering and complicate the enforcement of international norms.

Environmental Considerations in Armed Conflict

War’s impact on the environment is a growing concern within the framework of IHL. The destruction of ecosystems, contamination of water supplies, and long-term damage to agricultural lands not only harm civilians but also destabilize entire regions. Protocol I to the Geneva Conventions explicitly prohibits methods of warfare intended to cause “widespread, long-term, and severe damage to the natural environment.” For example, the use of defoliants like Agent Orange in the Vietnam War caused enduring ecological and health crises. Resistance movements and states alike must recognize that environmental destruction often leads to broader humanitarian disasters, further complicating post-conflict recovery.

Support for Resistance Movements

International Aid

Support for resistance movements, such as arms supplies or training, must comply with IHL. International actors face legal and ethical dilemmas in balancing assistance with respect for sovereignty and civilian protection. Humanitarian aid is universally permitted, but military aid often sparks significant geopolitical tensions.

Foreign Fighters

The involvement of foreign fighters in resistance movements complicates legal frameworks. Their status under IHL depends on adherence to combatant criteria and the laws of the conflict zone. Historical examples, such as international brigades during the Spanish Civil War, illustrate the complex interplay between international support and domestic resistance.

Humanitarian Access and Aid

Providing humanitarian aid in areas controlled by resistance forces raises unique challenges. Restrictions on access and targeting of humanitarian workers undermine civilian protections and violate IHL. Deliberate obstruction of humanitarian efforts, as seen in some contemporary conflicts, exacerbates civilian suffering and increases the likelihood of war crimes.

Public Perception and Propaganda

Propaganda can significantly influence the interpretation and application of IHL. Labeling resistance movements as “terrorists” often complicates their legal and ethical standing. The role of media in shaping public perceptions of lawful versus unlawful combatants is critical in modern conflicts. Counter-narratives by resistance movements can be essential in gaining international sympathy and support.

Ethical Dilemmas

Resistance fighters frequently face dilemmas, such as balancing operational effectiveness with civilian safety. Adhering to IHL can enhance their legitimacy and international support while reducing harm to civilians. Ethical conduct in warfare often serves as a strategic advantage, fostering broader political and diplomatic backing.

Case Study: Russia’s Actions in Ukraine

Russia’s invasion of Ukraine highlights numerous violations of IHL, including:

1. Indiscriminate Attacks: Bombardments of civilian infrastructure, including hospitals and schools, contravene the principle of distinction.
2. Use of Prohibited Weapons: Reports of cluster munitions and incendiary devices violating IHL have emerged.
3. Targeting Civilians: Documented instances of intentional attacks on non-combatants and protected classes undermine the core tenets of IHL.

These actions have prompted widespread condemnation and investigations into potential war crimes. The international response underscores the importance of documenting violations and pursuing accountability through legal and diplomatic channels.

Historical Precedents

Resistance movements throughout history offer valuable lessons on applying IHL:

• World War II: The French Resistance grappled with the dual challenge of effective operations and adherence to humanitarian principles.
• Vietnam War: The Viet Cong’s irregular tactics highlighted the complexities of distinguishing combatants from civilians.
• Anti-Colonial Struggles: Movements in Africa and Asia navigated the legal and ethical frameworks of resistance against colonial powers. These struggles underscore the challenges of achieving legitimacy under IHL while fighting against occupying forces.

Evolving Norms and Debates

Modernizing IHL

Debates about modernizing IHL to reflect contemporary conflict realities are ongoing. Proposals to strengthen civilian protections and address the use of new technologies in warfare are at the forefront. Enhanced accountability mechanisms and clearer guidelines for emerging forms of warfare are also central to these discussions.

Practical Guidance for Resistance Movements

Resistance groups can navigate IHL by adhering to principles such as distinction, proportionality, and precaution. Compliance with IHL enhances legitimacy, attracts international support, and minimizes civilian harm. Training and education on IHL can significantly improve adherence, even under challenging operational conditions.

Conclusion

International humanitarian law remains a cornerstone of efforts to humanize armed conflict. While its principles offer guidance for resistance movements and irregular combatants, practical challenges persist. Striking a balance between military effectiveness and ethical considerations is essential for preserving human dignity during war. The international community reaffirms its commitment to these ideals by holding violators accountable. The evolving nature of warfare necessitates continuous adaptation and reinforcement of these principles to address new challenges and protect those most vulnerable.
