Iran’s Proxies: Hamas, Hezbollah & Houthi Groups Explained | US Attacks

President Donald Trump’s recent authorization of strikes against targets in the region, framed as a response to Iran’s destabilizing activities, has brought renewed attention to the network of proxy groups Tehran supports across the Middle East. These groups, often referred to as Iran’s “Axis of Resistance,” represent a key component of the Islamic Republic’s regional strategy, extending its influence and challenging the established order. The U.S. Attacks, and the rhetoric surrounding them, underscore a deepening confrontation with Iran and its allies, a dynamic with complex historical roots and far-reaching implications.

The Architecture of Influence

Trump, in his announcement, directly accused Iran of arming, training, and funding terrorist militias responsible for violence throughout the region, from Lebanon and Yemen to Syria, and Iraq. As reported by the Los Angeles Times, the U.S. Is determined to prevent these proxies from further destabilizing the region and attacking American forces. Iran’s support for these organizations is multifaceted, encompassing military aid, financial assistance, and technical expertise. These groups, largely composed of Shiite Muslims, share a common ideological thread – opposition to U.S. And Israeli influence in the region and solidarity with the Palestinian cause.

It’s crucial to distinguish these Shiite-aligned groups from predominantly Sunni militant organizations like Al Qaeda and Islamic State. Although both sets of groups share animosity towards the United States and Israel, a deep sectarian divide exists between them, with Al Qaeda and Islamic State viewing Shiites as apostates and Iran as a primary adversary.

Hamas: A Longstanding, Complex Relationship

Hamas, the Palestinian Islamist organization controlling the Gaza Strip, was the only proxy group specifically named by Trump. Founded in 1987 during the First Intifada, Hamas initially received limited support from Iran, but this assistance increased significantly in the 1990s. Interestingly, early support for Hamas also came from Israel, according to Israeli press accounts, as a counterweight to the Palestine Liberation Organization (PLO). Since 2007, Hamas has functioned as both a military force and a governing body in Gaza, providing essential social services to the population.

The October 7, 2023, attacks launched by Hamas against Israel, resulting in the deaths of approximately 1,200 people and the abduction of 251 hostages, triggered the ongoing Israel-Hamas war. The conflict has resulted in over 70,000 Palestinian deaths in Gaza, according to the Hamas-run Gaza Health Ministry, a figure considered reliable by the United Nations and other observers. While Iran and Hamas share a common opposition to Israel, their sectarian differences – Iran being Shiite and Hamas Sunni – highlight the pragmatic nature of their alliance.

Hezbollah: Iran’s Most Potent Ally

Hezbollah, the Lebanese Shiite Islamist group, is widely considered Iran’s most powerful and strategically crucial proxy. Emerging from the Lebanese Civil War (1975-1990) and Israel’s 1982 invasion of Lebanon, Hezbollah has evolved into a major military and political force in Lebanon. The group receives substantial support from Iran, and its ideology is deeply rooted in the principles of the Islamic Revolution. Hezbollah maintains a significant presence in the Lebanese Parliament and operates an extensive social service network.

Hezbollah’s relationship with Iran extends beyond material support. The group’s founder and many of its leaders received religious and political training in Iran, particularly in the city of Qom, a center of Shiite scholarship. Hezbollah has engaged in numerous conflicts with Israel, including a 34-day war in 2006. Recent Israeli military campaigns have targeted Hezbollah, including the reported killing of a senior commander in 2024. The Los Angeles Times reported on the confirmation of the death of Hassan Nasrallah, a key figure in the organization.

The Houthis: Expanding the Reach into Yemen

The Houthis, officially known as Ansar Allah, represent Iran’s growing influence in Yemen, a country already grappling with a devastating civil war and humanitarian crisis. The Houthis seized control of Sanaa, the Yemeni capital, in 2014, and have since controlled large portions of the country, including a strategic stretch of the Red Sea coast. Iran has provided the Houthis with weapons, training, and financial assistance, despite the Houthis adhering to a different branch of Shiite Islam than the dominant sect in Iran.

Since the start of the Israel-Hamas war, the Houthis have launched attacks against Israel and commercial vessels in the Red Sea, claiming they are targeting ships linked to Israel. These attacks have disrupted global shipping lanes and prompted international concern. Trump noted the Houthis’ “toughness” and fighting capabilities, even after a previous bombing campaign aimed at curbing their attacks.

Iraqi Groups and the Legacy of Suleimani

The 2003 U.S.-led invasion of Iraq and the subsequent overthrow of Saddam Hussein created a power vacuum that allowed Iran to expand its influence in the country. A number of Iran-aligned Shiite militias emerged, many of which were hostile to the U.S. Presence. These militias are now formally part of the Iraqi armed forces, but continue to receive support from Iran’s Islamic Revolutionary Guard Corps (IRGC).

Qasem Suleimani, the commander of the IRGC’s Quds Force, played a pivotal role in cultivating and supporting these Iraqi militias. His assassination in a U.S. Drone strike in January 2020, alongside several militia commanders, marked a significant escalation in tensions between the U.S. And Iran. Suleimani was instrumental in building Iran’s network of proxies and coordinating attacks against U.S. Forces in Iraq, resulting in the deaths of hundreds of American troops.

What’s Confirmed and What Remains Unclear

The extent of Iran’s financial and military support for its proxies is largely confirmed by U.S. Intelligence assessments and corroborated by reports from regional analysts. Though, quantifying the precise level of assistance remains challenging. Similarly, the ideological alignment between Iran and its proxies is well-established, but the degree of operational control Iran exerts over these groups is a subject of debate. While Iran provides support and guidance, the proxies often operate with a degree of autonomy, pursuing their own agendas and responding to local conditions.

The long-term consequences of the U.S. Strikes against Iran and its proxies are also uncertain. While the stated goal is to deter further attacks and de-escalate tensions, the strikes could potentially provoke retaliatory actions and further escalate the conflict. The situation remains highly volatile and unpredictable.

Looking Ahead: A Complex Calculus

The current escalation is unfolding against a backdrop of ongoing negotiations between Iran and the United States, aimed at reaching a nuclear agreement. As detailed by Wikipedia, talks began in April 2025, but were interrupted by Israel’s attack on Iran. The future of these negotiations, and the broader relationship between the U.S. And Iran, will depend on a complex calculus of factors, including domestic political considerations, regional dynamics, and the evolving geopolitical landscape. The role of Iran’s proxy network will undoubtedly remain a central issue in any future discussions, as the U.S. Seeks to limit Iran’s regional influence and prevent further destabilization. The coming months will likely see continued diplomatic efforts, alongside the potential for further military escalation, as the U.S. And Iran navigate this increasingly dangerous and complex situation.
