U.S. policy toward Iraq continues to rest on an assumption that no longer reflects reality: that Iraq functions as a coherent partner with centralized authority over its security institutions.
It does not.
What exists instead is a fragmented system in which formal state structures operate alongside powerful internal networks, including actors aligned with Iran’s Islamic Revolutionary Guard Corps and its Quds Force. These actors are not external to the Iraqi state. They are embedded within it, shaping decision-making, access, and operational outcomes from inside the system.
IRAQ’S OIL LIFELINE IS BREAKING: THE BIGGEST STATE CASUALTY OF HORMUZ CRISIS
This distinction is no longer academic. It is strategic.
Washington continues to engage Iraq through ministries, formal chains of command, and institutional frameworks designed for a unified state. But Iraq’s security architecture no longer operates that way. Authority is layered, overlapping, and often informal. Analysis from organizations such as the Center for Strategic and International Studies has repeatedly highlighted how Iraq’s security environment is defined by competing power centers and fragmented authority structures that complicate external engagement.
The Popular Mobilization Forces illustrate this problem clearly. While formally incorporated into Iraq’s security apparatus, many of their most powerful factions maintain independent command structures and long-standing ties to Iran. Some openly align with Tehran’s strategic objectives. Others operate in parallel to official chains of command.
Reporting from the Special Inspector General for Iraq Reconstruction has consistently pointed to the same issue: Parallel security structures and weak institutional control continue to undermine governance, coordination, and accountability.
The result is a system where state authority exists on paper but is contested in practice.
For U.S. policymakers, the consequences are significant.
Security cooperation depends on clarity of command, reliability of counterparts, and confidence in information-sharing channels. In Iraq today, each of these conditions is increasingly uncertain. Coordination may involve actors with competing interests. Sensitive information may pass through networks that are not fully secure. Operational planning may rely on institutions that do not exercise full control over their own forces.
Assessments from the U.S. Department of War have long emphasized that partner-based operations require trusted counterparts and coherent command structures — conditions that are increasingly variable in Iraq.
These are not isolated risks. They are structural features of the environment.
Iran’s strategy in Iraq has not relied on overt domination. Instead, it has focused on long-term integration, building influence through political factions, militia networks, and relationships within state institutions. This approach allows Tehran to shape outcomes without formally controlling the system or triggering the kind of response that direct confrontation might provoke. The result is a system that is formally sovereign but functionally penetrated.
The problem for Washington is not a lack of capability. It is a mismatch between policy assumptions and operational reality.
U.S. strategy continues to treat Iraq as a traditional partner environment. But effective partner-based operations require a level of institutional coherence and autonomy that Iraq’s current system does not consistently provide.
If this gap remains unaddressed, the risks will continue to grow not only for U.S. objectives but for U.S. personnel operating in and around Iraq.
A more effective approach begins with recognizing how Iraq’s system actually functions.
First, U.S. engagement should be based on demonstrated reliability, not formal designation. Institutions and units should be evaluated based on transparency, autonomy, and operational behavior, rather than simply on their place within official structures.
Second, force protection frameworks must expand to account for internal system risks. This includes vulnerabilities in coordination channels, information-sharing pathways, and institutional exposure, not just external threats.
Third, U.S. policy must explicitly account for Iranian-aligned actors operating within Iraqi institutions. Ignoring this reality does not reduce its impact. It increases the likelihood of strategic miscalculation.
FRIEND OR FOE? HOW IRAN’S INFLUENCE OVER IRAQ SHOULD SHAPE US DIPLOMATIC APPROACH
Iraq remains strategically important. Continued U.S. engagement is necessary. But engagement based on outdated assumptions will reduce effectiveness and increase risk over time.
Washington does not need a new mission in Iraq. It needs a more realistic understanding of the environment in which it is already operating.
