Proxy Warfare

SyllabusRole of external state and non-state actors

Internal SecurityPublished 3 August 2026

Proxy warfare is the indirect pursuit of a state's strategic objectives through another state, an armed group or other non-state actor instead of openly deploying its own forces. It becomes state-sponsored terrorism when a state enables proxy groups to use terrorist violence, intimidation or coercion while concealing or limiting its own responsibility. Not every proxy conflict is terrorism, because a proxy may engage primarily in conventional or guerrilla combat against military targets.

How state sponsorship operates

The relationship may range from limited assistance to close direction; a proxy can retain its own ideology, leadership and objectives.

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

Why states use proxies

Proxy warfare offers a means of applying pressure below the threshold of acknowledged interstate war.

  • Plausible deniability can complicate attribution and delay diplomatic, legal or military responses.
  • It can reduce the sponsor's financial, military and domestic political costs compared with direct intervention.
  • It may be used to destabilise an adversary, weaken its institutions, influence negotiations or sustain a prolonged war of attrition.

Security implications 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.
  • The proxy may become autonomous, pursue divergent goals or create escalation and blowback for its sponsor.
  • An effective response combines intelligence sharing, border and coastal security, counter-terror financing, lawful investigation, diplomatic pressure and international cooperation.
  • Institutional resilience and public trust are necessary to prevent terrorists from exploiting social divisions.
