The Rise of Proxy Wars. How Iran Uses Militias to Fight Israel


The conflict between Iran and Israel is one of the most complex and prolonged rivalries in the Middle East. While the two countries have never fought a full-scale war directly, they are locked in a constant state of confrontation through proxy warfare. Iran’s strategy of using regional militias and armed groups to challenge Israel has reshaped Middle Eastern geopolitics and created a multi-front battlefield.

In this blog, we will explore how Iran has developed, supported, and deployed proxy forces to indirectly confront Israel, the groups involved, their objectives, and the consequences of this shadow war.

What is a Proxy War?

A proxy war occurs when two or more powerful countries support third-party groups or militias to fight on their behalf instead of engaging in direct military conflict. This allows the main actors to avoid direct retaliation or international consequences, while still pursuing strategic objectives.

In the case of Iran and Israel, proxy warfare enables Iran to apply pressure on Israel from different borders and regions, without launching a formal war.

Why Iran Uses Proxies

Iran’s use of proxy forces against Israel is part of a broader military and ideological strategy. Here are the primary reasons behind this approach:

  1. Avoiding Direct Conflict: Iran cannot match Israel’s advanced air force, intelligence, and cyber capabilities in a direct war. Using proxies helps Iran avoid full-scale military confrontation.

  2. Plausible Deniability: Supporting groups like Hezbollah or Hamas allows Iran to deny involvement in attacks on Israel, which helps it avoid international sanctions or military response.

  3. Regional Influence: Iran aims to expand its influence in the Middle East and create a “Shia Crescent” stretching from Iran through Iraq, Syria, and Lebanon. Proxies are the tools for this ambition.

  4. Ideological Warfare: Iran positions itself as the defender of Palestine and the Muslim world against “Zionist occupation.” Supporting groups that fight Israel helps it maintain this image among Muslim populations.

Key Iranian Proxy Groups Fighting Israel

Iran supports a network of non-state actors and militias that directly or indirectly attack Israeli targets or challenge its interests. Some of the most prominent among them include:

Hezbollah (Lebanon)

  • Founded: 1985

  • Location: Southern Lebanon

  • Support: Financed, trained, and armed by Iran’s Islamic Revolutionary Guard Corps (IRGC)

  • Strength: Estimated 100,000+ fighters; tens of thousands of rockets and missiles

  • Role: Hezbollah is Iran’s most powerful proxy and the biggest threat to Israel on its northern border. It has engaged in multiple skirmishes with Israeli forces and launched attacks during the 2006 Israel-Hezbollah war.

Hamas (Gaza Strip)

  • Founded: 1987

  • Location: Gaza

  • Support: Financial and military support from Iran

  • Role: Hamas governs the Gaza Strip and frequently launches rockets into southern Israel. Iran helps them with weapons technology and tunnel construction. Their most significant attack was the October 7, 2023 massacre, which led to Israel’s large-scale retaliation.

Palestinian Islamic Jihad (PIJ)

  • Founded: 1981

  • Location: Gaza

  • Support: Fully backed by Iran

  • Role: Smaller than Hamas but considered more militant. Frequently launches rocket attacks on Israel and collaborates with Hamas in operations against Israeli forces.

Popular Mobilization Forces (PMF) in Iraq

  • Location: Iraq

  • Support: IRGC influence; some factions directly answer to Tehran

  • Role: While primarily active against U.S. forces in Iraq, some PMF groups have expressed support for the Palestinian cause and could participate in broader conflicts against Israel if directed by Iran.

Houthi Rebels (Yemen)

  • Founded: Early 2000s

  • Location: Yemen

  • Support: Military and financial assistance from Iran

  • Role: Though their primary war is against Saudi Arabia, the Houthis have threatened Israel and have launched missiles toward Israel during times of escalated tension.

Shia Militias in Syria

  • Location: Syria

  • Support: Commanded or advised by the IRGC

  • Role: Positioned close to Israeli borders in the Golan Heights. These militias help Iran entrench its military presence in Syria and create another front against Israel.

Iran’s Tools and Tactics

Iran doesn’t just provide money—it trains, arms, and coordinates operations with its proxies through the IRGC Quds Force, a special branch tasked with foreign operations.

Iran’s involvement includes:

  • Missile Technology: Iran supplies short-range and medium-range missile technology to Hezbollah and Hamas.

  • Drone Warfare: Iranian drones have been used by proxies in Lebanon, Syria, Iraq, and Gaza.

  • Cyber Capabilities: Iran helps proxies develop cyber tools to target Israeli infrastructure.

  • Tunnel Networks: Iran has aided Hamas in developing underground tunnels for smuggling weapons and launching surprise attacks.

  • Training Camps: Iran runs training facilities for foreign fighters from Lebanon, Iraq, Syria, and Yemen.

How Israel Responds to Iran’s Proxy Strategy

Israel has responded aggressively to Iran’s proxy threats, especially in Syria and Lebanon:

  1. Airstrikes in Syria: Israel has carried out hundreds of airstrikes on Iranian positions and weapons convoys in Syria.

  2. Targeted Killings: Israeli intelligence has conducted assassinations of key Iranian operatives and Hezbollah leaders.

  3. Iron Dome and Missile Defense: Israel has heavily invested in air defense systems like Iron Dome, David’s Sling, and Arrow to intercept rocket and missile attacks.

  4. Diplomatic Pressure: Israel works with the United States and other allies to label these groups as terrorist organizations and sanction Iran.

Consequences of Proxy Warfare

The widespread use of proxies has destabilized large parts of the Middle East and caused significant humanitarian suffering:

  • Civilian Casualties: Thousands of innocent people in Gaza, Lebanon, Syria, and Israel have died due to rocket fire, bombings, and military responses.

  • Refugee Crises: Conflicts in Syria, Lebanon, and Yemen have displaced millions.

  • Regional Tensions: Proxy wars have drawn in multiple countries, including Saudi Arabia, the U.S., Russia, and Turkey.

  • Risk of Full-Scale War: As seen in 2024, Iran’s direct missile attacks and Hezbollah’s involvement in Israeli conflicts can escalate into a major regional war.

Is There an End to Proxy Wars?

Ending proxy wars is extremely difficult because:

  • Iran sees them as essential tools for influence.

  • Israel considers them existential threats.

  • The international community is divided.

Any long-term solution would require:

  • A new nuclear agreement or regional security pact

  • Political reforms within Lebanon, Gaza, Iraq, and Syria

  • Diplomatic engagement between Iran and regional powers

  • U.S. and international pressure on Iran to scale down its regional military networks

Conclusion

The rise of proxy warfare has allowed Iran to expand its influence while maintaining a buffer against direct retaliation. For Israel, this strategy has created multiple active threats along its borders and forced it to maintain a constant state of alert. These shadow wars have turned entire regions into war zones, and without international mediation, they may soon erupt into a broader, more destructive conflict.

The Iran-Israel rivalry will likely continue to be fought not only on battlefields, but also through militias, missiles, and minds—a long, complex war with no easy end in sight.
