Iran’s evolving approach to state capture in Iraq shows how the old line between state institutions and non‑state proxies has largely dissolved. Instead of relying solely on militias and their political fronts, Tehran has used the post‑2003 ethno‑sectarian power‑sharing system to place loyalists deep inside Iraq’s governing structures. In doing so, it has steadily reshaped state bodies into tools for advancing its regional and global agenda.
This penetration reached key ministries—including the Ministry of Foreign Affairs—allowing Iran to harness legitimate diplomatic channels for intelligence gathering, logistical support, and strategic outreach well beyond Iraq’s borders. Unlike militias, the use of Iraq’s official diplomatic apparatus grants Iran legal cover, protected communications, sovereign legitimacy, and international reach. The result is clear: Iran’s influence is no longer operating merely alongside the Iraqi state, but increasingly through it.

A telling case is that of Rajeh Al‑Moussawi, a senior figure in the Iraqi Hezbollah movement, who moved seamlessly from serving as Basra’s deputy governor to holding ambassadorships in Azerbaijan and Iran. His son, Wissam Rajeh Al‑Moussawi, mirrored his rise, when he secured the strategically vital post of Iraqi Consul in Ahvaz—a key cross‑border hub. This dual generation placement reflects a rooted patronage strategy that ensures Iraq’s diplomatic protections, diplomatic pouches, and unmonitored communication channels remain aligned with operational Iranian needs.
By controlling these consular chokepoints, the network can circumvent standard international border controls and move funds, intelligence operatives, and specialized materiel under the full legal immunity afforded by the Vienna Convention. These patterns indicate that certain diplomatic appointments function less as merit‑based postings and more as extensions of embedded political networks operating from within the Iraqi state.
The financial realities of this institutional capture demonstrate how Iraq’s massive oil revenues actively underwrite Iran’s regional ambitions. Baghdad regularly establishes and finances diplomatic missions in geographically strategic regions solely to provide an operational footprint for the Islamic Revolutionary Guard Corps and Lebanese Hezbollah. In cases where Iran faces direct financial restrictions or political barriers, Iraq covers all the embassy operational expenses, including staff salaries for the foreign missions in Baghdad representing countries and entities vital to Tehran’s geopolitical orbit, such as Sudan, Somalia, and the Palestinian Authority. This financial underwriting extends beyond the Middle East.

Brazil illustrates this dynamic. Despite Brazil’s refusal to establish full diplomatic relations with post-2003 Iraq until resolution of outstanding debts, Iraq maintained an embassy in Brasília. Iraqi Ministry of Foreign Affairs records reportedly indicated that only 40 Iraqi citizens resided in Brazil as of 2017. The scale of this diplomatic presence appears disproportionate to direct consular demand, raising questions about the strategic utility of such postings within broader regional frameworks, including Latin America. A more plausible explanation lies in the operational utility that Iraqi diplomatic infrastructure provides for Iranian activities in Latin America.
This institutional infiltration accelerated during the counter-Islamic State campaign after 2014. While international attention focused on defeating the Islamic State, Iran and its aligned actors expanded their influence within Iraq’s foreign-policy bureaucracy. During Ibrahim Al-Jaafari’s 2014–2018 tenure as foreign minister, the Foreign Ministry engineered bureaucratic nodes to integrate Iranian-trained intelligence elements directly into the state’s diplomatic apparatus. Chief among these was the Ministry of Foreign Affair’s counter-terrorism office detached to the minister’s own office, ostensibly designed to interface with international and regional partners after the United States excluded Russia and Iran from the Global Coalition against the Islamic State.
Ground network mapping reveals that this office functioned as a bureaucratic laundry facility transitioning operatives—mainly from the Iraqi National Security Service, many with extensive Iranian training—into legitimate diplomatic posts.
Being aware of the problem and having the ability to disrupt it are two different questions, which political will and State Department diplomatic calculations also color.
Ahmed Al-Sahhaf’s service trajectory was from the Iraqi National Security Service to the Ministry of Foreign Affairs’ Counter-Terrorism Office, and subsequently, to become the Foreign Ministry spokesman in 2017. Al-Sahhaf held this influential post until his 2023 appointment as charge d’ affaires in Libya, after which the spokesperson position again became vacant—illustrating the cynical Iranian use of nodes to protect and amplify those serving its agenda.
As early as 2017, the United States appeared to become aware, through its own means, of how the Iraqi foreign ministry was transmitting encrypted communications to various embassies to the benefit of Islamic Revolutionary Guard Corps networks, as well as the routine abuse of the Iraqi diplomatic pouches. Being aware of the problem and having the ability to disrupt it are two different questions, which political will and State Department diplomatic calculations also color.
The recent issuance of Iraqi government service passports—usually granted to senior officials—to high-level Islamic Revolutionary Guard Corps-linked operatives heightens the threat. The U.S. arrest and federal indictment of Mohammad Al-Saadi, an operative tied to Kata’ib Hezbollah and the Qods Force, revealed the consequence of this weaponization.
Al-Saadi’s ability to traverse international borders using official Iraqi state credentials exposes how Iranian actors have penetrated the state’s sovereign machinery, turning routine bureaucratic mechanisms into instruments of international terrorism and sanctions evasion, challenging international security, and mandating scrutiny from U.S. intelligence and policymakers for Iraqi diplomatic activities undertaken by Iranian-backed actors. For Washington to continue to ignore such abuses increasingly constitutes diplomatic and national security negligence.
