Shifting Shadows: How Washington Abandoned Global Leadership on Civilian Harm Mitigation—And How Europe Stepped In

BRUSSELS — Three years ago, the corridors of the Pentagon echoed with an ambitious, hard-fought vision. Forged in the bloody crucible of post-9/11 "forever wars" across Iraq and Afghanistan, the Department of Defense spearheaded an international coalition aimed at fundamentally transforming how modern militaries protect noncombatants.

Today, that architecture of accountability stands largely hollowed out from within. Under the directive of Defense Secretary Pete Hegseth—who has frequently dismissed rules of engagement and humanitarian guardrails as "woke"—the United States has abruptly abandoned its premier role in civilian protection.

That sudden vacuum was laid bare this week at NATO headquarters in Brussels. As defense officials, diplomats, academics, and humanitarian advocates gathered for a high-stakes summit of the International Contact Group on Civilian Harm Mitigation and Response (CHMR), the American delegation was entirely absent. Once the architect and primary driver of global standards for sparing civilian lives, the United States has traded international leadership for isolation, leaving European allies to carry the torch forward on their own.

Current and former defense officials, speaking to ProPublica on the condition of anonymity for fear of professional retaliation from President Donald Trump’s administration, did not mince words. They characterized Washington’s withdrawal from the forum as both "humiliating" and "dangerous." This policy reversal, critics argue, arrives at a perilous moment marked by rising civilian casualties and devastating strikes on residential neighborhoods and schools in conflicts involving U.S. and allied operations, most notably in Iran.

The Genesis of CHMR: Learning from the Bloody Lessons of Forever Wars

To understand the magnitude of the current retreat, defense analysts emphasize the arduous path it took to establish the CHMR framework in the first place. For decades, military terminology reduced the deaths of innocent men, women, and children to cold, bureaucratic calculus: "collateral damage."

The paradigm began to shift slowly following intense international outrage over civilian death tolls in Iraq and Afghanistan. Human rights advocates, military ethicists, and progressive commanders argued that not only were civilian casualties morally indefensible, but they were also strategically counterproductive. Every civilian death alienated local populations, fueled insurgencies, and handed propaganda victories to extremist networks.

In 2022, under the Biden administration, the Pentagon formally codified these lessons by adopting the Civilian Harm Mitigation and Response (CHMR) action plan—colloquially pronounced "chimmer." The framework represented a generational culture shift within the U.S. military. It mandated the creation of a specialized center dedicated to collecting, analyzing, and archiving strike data. Furthermore, it embedded civilian protection advisers directly inside regional combat commands to evaluate strike risks in real time.

Eager to export these hard-won lessons globally, Washington forged a partnership with the Netherlands—a close military ally in campaigns against the Islamic State group that was simultaneously reckoning with its own dark chapters in civilian accountability.

Most notably, the Dutch government faced a severe domestic scandal in 2019 when investigations revealed it had concealed its role in a 2015 airstrike in Hawija, Iraq. The strike, which targeted a car-bomb factory, inadvertently ignited a massive hidden munitions depot. The resulting cataclysmic blast killed at least 70 civilians and wounded hundreds more. Seeking redemption and reform, the Netherlands joined forces with the United States in 2023 to establish an informal, international coalition focused on sharing best practices, tracking trends, and developing unified standards for civilian protection.

Chronology of a Retreat: From Global Pioneer to No-Show

The timeline of America’s abdication from this vital mission can be traced through a rapid succession of policy shifts and personnel purges:

• 2022: The Pentagon officially adopts the CHMR framework, promising a new era of military transparency and operational restraint.
• 2023: The U.S. and the Netherlands co-found the International Contact Group on Civilian Harm Mitigation and Response, holding the first of several informal summits. Participating nations—including the U.K., Belgium, Germany, Norway, and Australia—begin aligning their defense doctrines with American insights.
• Early 2025: With a new administration taking power, Defense Secretary Pete Hegseth targets the CHMR program. Deriding humanitarian oversight as an impediment to military readiness, Hegseth dramatically guts the initiative. Staffing levels at the specialized civilian protection directorate plummet from nearly 200 personnel down to roughly two dozen, over the fierce objections of top-ranking U.S. military commanders.
• Late 2025 – Early 2026: U.S. participation in the international contact group ceases entirely. While international allies hold meetings without American representation, reports mount of escalating civilian casualties in Middle Eastern theaters, including devastating strikes in Tehran.
• Today: The Brussels NATO summit convenes. True to predictions by defense insiders, the U.S. roster is blank, signaling a definitive end to American stewardship over civilian harm mitigation.

Jenny McAvoy, a former Defense Department official who played a instrumental role in shaping the U.S. civilian protection program, reflected on the tragic irony of the situation.

"There will be a day when people who care about mitigating civilian harm can come back and say, ‘OK, are we ready to solve this problem?’" McAvoy said. "But there are already enormous consequences of abandoning this work."

McAvoy noted that when the United States initially put its credibility on the line by admitting past mistakes and vowing to improve, it provided vital diplomatic cover and moral permission for other nations to scrutinize and reform their own military doctrines.

"By the U.S. putting itself out there and saying, ‘We learned, we can do better,’ it gives permission and makes it OK for other governments to similarly acknowledge, ‘Yeah, we can do better too,’" she explained.

Supporting Data and the Brussels Agenda

The two-day summit in Brussels was meticulously structured to address the complex realities of modern warfare across land, sea, and coalition environments. According to a draft agenda reviewed by ProPublica, the conference opened with broad panels incorporating civil society organizations, academics, and humanitarian advocates. Discussions focused on tactical adaptations, data collection methodologies, and the legal obligations of armed forces during asymmetric conflicts.

The second day shifted behind closed doors for sensitive, high-level diplomatic sessions restricted to senior representatives of member states. Participating nations included a diverse array of European partners, such as Austria, Belgium, Denmark, Finland, Germany, Norway, the United Kingdom, and the Netherlands. Each country brings unique operational capabilities and domestic political pressures to the table.

For instance, the United Kingdom has historically lacked a formalized, comprehensive framework for civilian harm mitigation and response comparable to the defunct American model. For years, British human rights advocates have lobbied the Ministry of Defence to emulate U.S. standards.

Mae Thompson of the London-based Ceasefire Centre for Civilian Rights noted that while humanitarian groups viewed the American CHMR architecture as nascent and imperfect, it nonetheless established a gold standard for transparency. Thompson explained that advocacy groups now view the Pentagon’s self-inflicted retreat as an unexpected opening for the U.K. to step into a leadership vacuum.

Signs of this potential pivot are already emerging in London. A recent internal review by the British Ministry of Defence recommended formalizing a robust national program aimed at systematically tracking civilian harm, conducting rigorous post-strike investigations, and offering amends to affected noncombatants.

Official Responses and Bureaucratic Silence

Faced with mounting international criticism and pointed inquiries regarding its absence from the Brussels talks, the Pentagon has adopted a posture of defensive ambiguity.

When approached by journalists, the Department of Defense declined to issue a direct statement concerning its lack of representation at the NATO headquarters summit. However, a Pentagon spokesperson pointed to earlier talking points, asserting that the U.S. military continues to factor civilian protections into all operational planning phases.

"The Department remains committed to fulfilling its civilian harm mitigation and response responsibilities," the spokesperson maintained.

That reassurance rings hollow to military analysts and international observers who point to the systemic gutting of the office designed to enforce those very responsibilities. By reducing a dedicated staff of 200 experts down to a skeleton crew of roughly 24, critics argue the Pentagon has stripped itself of the analytical capacity required to effectively monitor, investigate, and prevent civilian casualties in high-intensity operational environments.

The human cost of this institutional retreat is starkly illustrated far from Brussels. In Tehran, foreign ambassadors and heads of diplomatic missions recently visited Resalat Square, where an outdoor exhibition displays photographs of men, women, and children killed in recent U.S. and allied airstrikes. The visual evidence of noncombatant fatalities stands as a grim indictment of a military apparatus operating with severely diminished internal oversight.

Global Implications: Europe Steps Up as Washington Steps Back

As the Brussels summit concluded with a forward-looking panel discussion, the overarching takeaway for foreign policy experts was clear: the era of uncontested American leadership in military humanitarianism has come to a close.

Yet, rather than collapsing entirely under the weight of Washington’s absence, the international coalition has demonstrated remarkable resilience.

Andrew Hyde, a specialist in U.S.-European relations at the nonpartisan Stimson Center, observed that international forums remain critical for navigating the legal and operational friction points that arise during joint military campaigns. When U.S., NATO, and European forces operate under divergent interpretations of harm mitigation, coordination is paramount.

According to Hyde, the diminished role of the United States forces European partners—led by the U.K. and the Netherlands—to accelerate their own institutional maturation. Ironically, this shift in the center of gravity could ultimately insulate global civilian protection standards from the erratic policy swings of successive U.S. administrations.

"The U.S. stopped participating in this group last year, and people assumed that meant the group would die," McAvoy noted. "But the group continued to exist and to meet—without the U.S.—under the leadership of the U.K. and the Netherlands."

Hyde echoed this sentiment, suggesting that international institutions are learning to insulate themselves against American retrenchment.

"NATO has continued to push forward without U.S. support or participation," Hyde said, "keeping up the momentum and ready for U.S. re-engagement whenever Washington decides to rediscover its moral compass."
