State Sovereignty and the Illegality of Arming Militias in Sudan: Debunking a Misleading Narrative

Public discourse around the war in Sudan often suffers from a critical conflation between two fundamentally different concepts in international law: a state’s sovereign right to engage in military cooperation, and unlawful intervention through arming non-state armed groups.

This confusion is frequently invoked to justify external support for the RSF militia, despite the absence of any legal or political basis for such a claim.

Unmistakably, as sovereign entities, states have the inherent right to form defence partnerships, receive military assistance, purchase weapons, or host training missions and bases.

This is a universally recognized prerogative exercised by states across the world, and it does not diminish their legitimacy or give any other state the right to interfere in their internal affairs.

However, in contrast, supplying weapons, training, or logistical support to armed groups operating outside state authority constitutes a form of "proxy aggression" .

It is a prohibited practice under international law because it undermines state sovereignty, fuels internal conflict, and exposes civilians to widespread violations and instability.

The essential difference rests on legality and responsibility: in one hand, the state is a recognized legal actor entitled to enter military agreements.

On the other hand, the militia is an illegitimate non-state entity, and supporting it amounts to direct interference in the domestic affairs of a sovereign country.

Hence, there should be no mistake, equating legitimate state-to-state cooperation with the unlawful arming of militias creates a misleading narrative.

It obscures accountability, distorts public understanding of the conflict, and downplays the severity of external involvement that threatens Sudan’s territorial integrity and civilian safety.

In conclusion, foreign military assistance to Sudan’s national armed forces falls within the domain of sovereign rights. Conversely, arming the RSF militia, with weapons or mercenaries, constitutes an unlawful intervention and a form of aggression by proxy.

As a matter of fact, recognizing this distinction is not a theoretical exercise—it is essential to understanding the nature of the conflict and safeguarding the stability and sovereignty of the Sudanese state.
