Iraq is once again confronting a grave political and security crisis as powerful Iran-backed Shiite armed factions defiantly refuse to lay down their weapons and submit to government authority. This standoff exposes the limits of Baghdad’s power and heightens fears of renewed internal conflict, drawing sharp warnings from both domestic reformists and the international community.
The roots of the current crisis trace back to the post-2003 security vacuum and the subsequent rise of the Islamic State (ISIS) in 2014. In response, dozens of predominantly Shiite paramilitary units—many with deep ideological and operational ties to Tehran—mobilized under the umbrella of the Popular Mobilization Forces (PMF). With crucial Iranian training, funding, and weaponry, these groups played a key role in defeating ISIS. However, long after the territorial defeat of the extremist group, they have refused to demobilize, instead transforming into entrenched political-military networks that now operate beyond the state’s effective control.
At the center of the current impasse are several well-known factions that openly reject disarmament and continue to expand their influence in violation of Iraqi law. Among them, the Badr Organization stands out as Iran’s oldest and most deeply embedded proxy, with members holding senior positions in state security institutions. Kata’ib Hezbollah, a designated terrorist group by the U.S., has carried out repeated attacks against American and coalition forces. Asa’ib Ahl al-Haq operates both a robust paramilitary wing and a significant political bloc in parliament. Other factions, including Harakat al-Nujaba and Kata’ib Sayyid al-Shuhada, remain active in regional operations, often acting as extensions of Iran’s Islamic Revolutionary Guard Corps (IRGC).
Iran’s strategic imperative: Tehran views these militias as indispensable instruments for preserving its influence in Iraq and countering perceived American encirclement. The Iranian regime, known for internal repression and regional interference, has consistently poured resources into these groups, enabling them to defy Baghdad’s repeated calls for disarmament and integration. By maintaining a network of loyal armed factions, Iran can undermine any Iraqi government reform effort that threatens its interests, while also using Iraqi territory as a launchpad for proxy warfare against U.S. targets and Israeli interests.
A government in a bind: Successive Iraqi prime ministers have pledged to bring all armed groups under state control, yet enforcement remains elusive. The current administration faces a stark dilemma: if it moves forcefully against the militias, it risks triggering violent clashes that could spiral into civil war; if it continues to tolerate their autonomy, it cedes sovereignty and invites further international isolation. This paralysis has emboldened the armed factions, which now openly flaunt their military capabilities and deepen their economic and political entrenchment.
The deadlock carries severe implications for Iraq’s domestic and foreign affairs. Domestically, the presence of parallel armed forces undermines the rule of law, fuels sectarian tensions, and diverts resources away from reconstruction and development. The pervasive atmosphere of intimidation restricts political pluralism and hampers the growth of a genuinely independent state. Internationally, the continued activities of these militias complicate Iraq’s relations with Western powers and Sunni Arab neighbors, who worry about Iran’s expanding footprint. U.S. officials have repeatedly conditioned continued military and economic support on meaningful steps to restrain Iranian proxies.
International concern and calls for action: The international community—including the United Nations, the United States, and European Union—has expressed deep alarm at the situation. Diplomatic pressure is mounting on Baghdad to enforce its own laws and fulfill its obligations under international agreements that require the state to maintain a monopoly on the legitimate use of force. However, without tangible leverage or a unified regional strategy, external actors have struggled to alter the dynamics on the ground.
Looking ahead: Without a concerted domestic and international push to disarm these groups, Iraq risks sliding back into large-scale violence. A revitalized political compact, backed by robust international support and clear red lines for Iran’s interference, may offer a path out of the current crisis. For now, the refusal of Iran-backed Shiite militias to disarm remains a central obstacle to Iraq’s quest for stability, sovereignty, and a meaningful break from cycles of conflict.
