Proxy Warfare

Proxy warfare is a form of interstate competition in which a state pursues strategic objectives indirectly through another state, an armed group or another non-state actor instead of openly deploying its own forces. The sponsor supplies support or direction while the proxy may retain its own ideology, leadership and objectives. It becomes state-sponsored terrorism when the proxy uses terrorist violence, intimidation or coercion with state support; not every proxy conflict is terrorism.

The sponsor-proxy relationship

Proxy warfare is defined by indirect state involvement, although sponsorship can range from limited assistance to close direction.

• Sponsorship may include finance, weapons, training and intelligence, supplied directly or through intermediaries.
• A sponsor may provide safe havens, recruitment networks, documents, communications and logistical routes.
• Political advocacy, propaganda and diplomatic protection can help the proxy gain legitimacy or evade accountability.
• Proxies may conduct conventional or guerrilla combat, cross-border infiltration, sabotage, targeted killings or attacks intended to spread fear among civilians.

Why states use proxies

Proxies allow states to exert pressure below the threshold of acknowledged interstate war and compete without assuming the full costs of direct intervention.

• Plausible deniability can complicate attribution and delay diplomatic, legal or military responses.
• Indirect action can reduce the sponsor's financial, military and domestic political costs.
• A proxy may destabilise an adversary, weaken its institutions, influence negotiations or sustain a prolonged war of attrition.

Security consequences and response

Proxy terrorism blurs the boundary between internal disorder and external aggression, making intelligence-led attribution and coordinated action essential.

• It can intensify communal fear, damage economic activity and overstretch police, intelligence and border-management institutions.
• A proxy may become autonomous, pursue divergent goals or cause escalation and blowback for its sponsor.
• Responses include intelligence sharing, border and coastal security, counter-terror financing, lawful investigation, diplomatic pressure and international cooperation.
• Institutional resilience and public trust help prevent proxy groups from exploiting social divisions.
