Proxy Wars Explained: Why Powerful States Fight Through Other Actors
Wars are not always fought directly between the countries competing for power.
Sometimes a government wants to weaken a rival, expand its regional influence or protect an important strategic interest without sending its own military into a full-scale confrontation. Instead, it may provide weapons, money, intelligence, training or political support to another government or armed group already involved in a conflict.
This is the basic logic behind proxy warfare.
RAND defines proxy wars as conflicts in which an outside state supports a local party with resources useful for armed conflict—including funding, weapons, equipment, training, intelligence, advisers or even troops—to achieve a strategic objective.
Proxy warfare is particularly important to modern global security because it can allow powerful states to compete while reducing some of the immediate political and military costs of fighting each other directly.
But indirect warfare does not necessarily make conflict safer.
It can prolong wars, strengthen armed groups, complicate peace negotiations and create escalation risks that extend far beyond the original battlefield.
What Is a Proxy War?
A proxy war occurs when an outside power supports another actor participating in an armed conflict in pursuit of its own strategic interests.
The proxy can be a government, rebel movement, militia or another organized armed actor.
Support can take many forms:
- weapons and ammunition;
- military training;
- intelligence and surveillance;
- financing;
- advisers;
- logistical assistance;
- diplomatic protection;
- technological support.
The International Committee of the Red Cross describes proxy warfare broadly as hostilities involving state or non-state actors receiving direct or indirect political, financial, material or military support from other actors pursuing their own strategic interests.
The important point is that a proxy is not necessarily a puppet.
Local actors normally have their own political objectives, territorial ambitions and security concerns. Their interests may overlap with those of their sponsor without being identical.
That difference becomes extremely important when trying to understand why proxy relationships can become difficult to control.
Why Do Powerful Countries Use Proxies?
The most obvious reason is risk reduction.
Direct war between major military powers can produce enormous casualties, economic disruption and escalation.
The danger becomes considerably greater when nuclear-armed states are involved.
Supporting another actor offers governments an alternative way to influence events.
A sponsor may help a partner defend territory, weaken an adversary, increase bargaining leverage or preserve influence in a strategically important region without deploying a conventional army on the same scale.
Proxy strategies can also be cheaper than major military interventions.
Local forces already understand the geography, language, political environment and battlefield conditions.
But these advantages come with a major weakness:
the sponsor does not completely control the proxy.
A local armed group can pursue objectives its sponsor does not want, escalate unexpectedly or refuse a political settlement.
That principal-agent problem is one of the fundamental risks of proxy warfare.
Proxy Wars and Great-Power Competition
Proxy warfare became particularly prominent during the Cold War.
The United States and Soviet Union competed globally while trying to avoid a direct military confrontation that could potentially escalate into nuclear war.
Local and regional conflicts consequently became arenas for wider geopolitical competition.
The modern international system is different, but the underlying strategic logic remains relevant.
Military assistance, intelligence cooperation, sanctions, private military actors, drones, cyber capabilities and local partnerships can all allow governments to compete below the threshold of direct interstate war.
Understanding those relationships also requires understanding how alliances operate. Global Power Desk's guide to NATO Explained examines how collective defense differs from the much looser relationships often seen between sponsors and proxy actors.
This distinction matters.
An alliance normally involves recognized governments and formal or informal security commitments. A proxy relationship can involve much greater ambiguity about responsibility and control.
How Modern Proxy Warfare Has Changed
Modern technology has dramatically expanded what outside sponsors can provide.
A proxy force once dependent mainly on rifles, ammunition and money can now potentially receive sophisticated drones, satellite information, secure communications, electronic warfare support and precision weapons.
Air and missile threats are particularly important because relatively inexpensive systems can create significant defensive challenges.
Our explainer on Air Defense Systems Explained examines how modern militaries attempt to detect and intercept aircraft, missiles and drones.
Technology has also expanded proxy competition beyond physical battlefields.
Cyber operations can offer governments another layer of deniability because attribution is often more complicated than identifying conventional military forces crossing a border.
The United Nations has warned that proxy actors can also operate in cyberspace through espionage, disinformation and digital attacks, further blurring traditional distinctions between state and non-state activity.
That makes Cyber Warfare Explained an increasingly important part of understanding modern indirect conflict.
Why Proxy Wars Can Last So Long
External support can dramatically change the balance of a local war.
A weaker actor that might otherwise lose can continue fighting when an outside sponsor supplies weapons, money or intelligence.
If the opposing side receives support from another external power, both parties may gain enough resources to continue the conflict without becoming strong enough to achieve a decisive victory.
This can create a dangerous cycle.
Local conflict → outside intervention → stronger armed groups → prolonged fighting → deeper outside involvement.
Eventually, ending the war may require agreement not only among the forces actually fighting but also among their external sponsors.
This is one reason proxy conflicts can become exceptionally difficult diplomatic problems.
Proxy Warfare and Russia
Russia provides an important case for understanding how conventional military power can interact with indirect instruments.
Moscow's security strategy has historically included conventional forces, intelligence operations, local partnerships and other forms of influence depending on the theater and period involved.
But terminology matters. Not every conflict involving outside military support is automatically a proxy war, and analysts disagree over how broadly the term should be applied.
Understanding the conventional side first helps clarify that distinction. Our guide to Russia's Military Structure Explained breaks down how Russia organizes its armed forces and command structure.
The broader lesson applies beyond Russia: direct intervention and proxy warfare can coexist, but they are not identical concepts.
The Middle East and Proxy Competition
The Middle East has provided some of the clearest modern examples of external powers supporting local armed actors.
Conflicts in Syria, Yemen, Iraq and Libya have involved varying combinations of local governments, armed movements, regional powers and outside states.
However, calling every armed organization a “proxy” can oversimplify reality.
Many groups possess substantial autonomy.
They may accept weapons or financial assistance from another government while maintaining independent leadership, ideology and political goals.
That is why responsible geopolitical analysis should distinguish between documented support and assumptions that a sponsor controls every decision made by a supported organization.
Economic Warfare Can Accompany Proxy Warfare
Military support is only one tool states use against competitors.
Economic pressure frequently operates alongside indirect military competition.
Governments can impose sanctions, restrict financial transactions, limit access to technology or target strategic industries while simultaneously supporting partners elsewhere.
This creates a broader contest involving both military and economic instruments.
Global Power Desk's guide on how sanctions affect international business explains how restrictions imposed for geopolitical reasons can spread through banking, trade, investment and global supply chains.
For major powers, the combination of economic pressure and indirect military support can offer alternatives to direct war—but can also deepen long-term confrontation.
The Problem of Accountability
Proxy warfare creates difficult questions under international law.
If an armed group commits abuses while receiving foreign weapons or financing, how much responsibility belongs to the external sponsor?
The answer depends heavily on the facts and applicable legal standards.
The ICRC stresses that international humanitarian law continues to apply where the legal conditions for an armed conflict are met; describing a situation as “proxy warfare” does not create a legal vacuum.
This becomes especially important when relationships between sponsors and armed groups are deliberately kept ambiguous.
Deniability may provide political advantages, but it can also make accountability more difficult.
Can Proxy Wars Prevent Bigger Wars?
This is one of the most difficult questions.
There is a strategic argument that indirect competition can sometimes provide powerful states with ways to confront each other without immediately entering direct war.
From that perspective, proxy warfare may act as a buffer against an even more destructive confrontation.
But there is an opposite danger.
A proxy can attack something its sponsor did not intend.
A rival can conclude that the sponsor was responsible.
Retaliation can follow.
The sponsor may then feel compelled to defend its partner or reputation.
What began as indirect competition can therefore create an escalation ladder toward direct confrontation.
Proxy warfare does not eliminate risk.
It redistributes it.
Why Proxy Wars Matter for World Security
Modern security competition increasingly operates across several domains simultaneously.
States can use conventional forces, economic sanctions, cyber operations, intelligence services, drones, diplomatic pressure and relationships with local armed actors.
Proxy warfare sits inside this wider security environment.
The United States' broader use of alliances, military deployments, sanctions and diplomacy is explored in US Foreign Policy Explained.
Understanding these different tools helps explain why modern geopolitical competition cannot always be divided neatly into “war” and “peace.”
Countries may avoid formally declaring war while still competing intensely through economic, technological, political and military means.
Conclusion
Proxy wars allow powerful states to pursue strategic objectives without necessarily committing themselves to full-scale direct military confrontation.
That can make proxy warfare attractive—but also dangerous.
External support can strengthen weaker partners, extend a sponsor's influence and impose costs on rivals. Yet the same strategy can prolong conflicts, empower armed groups, complicate accountability and create escalation that sponsors may eventually struggle to control.
Technology is making the picture even more complex.
Drones, cyber operations, precision weapons, intelligence networks and digital influence campaigns mean that modern proxy competition can extend far beyond traditional battlefields.
Understanding proxy wars therefore means understanding one of the central realities of modern world security:
Great powers do not always need to fight each other directly to compete militarily.
And sometimes, avoiding direct war between powerful states transfers the greatest human and economic costs to the countries where their competition plays out.

Frequently Asked Questions
What is a proxy war in simple terms?
A proxy war is a conflict in which an outside power supports another government or armed group to advance its own strategic interests rather than relying entirely on direct military intervention.
Why do countries use proxy forces?
They may seek lower costs, local battlefield knowledge, political deniability or a way to pressure rivals while reducing the immediate risks associated with direct interstate war.
Are proxy groups completely controlled by their sponsors?
Not necessarily. Proxy relationships vary considerably, and supported groups can maintain their own leadership, interests and objectives.
Are proxy wars illegal?
“Proxy war” is a strategic description rather than a separate legal category. The applicable international law depends on the actual circumstances and legal classification of the conflict. The ICRC emphasizes that international humanitarian law applies when the relevant conditions for armed conflict are satisfied.
Can cyberattacks be part of proxy warfare?
Yes. States can potentially rely on or support outside actors for cyber espionage, disruption, influence operations or other digital activities. The UN has specifically highlighted the growing role of proxy-type actors in cyberspace.
Why are proxy wars dangerous for global security?
They can prolong local conflicts, complicate accountability and diplomacy, spread weapons and military technology, and potentially trigger direct confrontation between the external powers supporting opposing actors.
