Five former United States officials, including a former Pentagon deputy general counsel for the laws of armed conflict, signed a Wednesday-evening letter to Defense Secretary Pete Hegseth and the Senate Armed Services Committee describing the Department of Defense's nine-week silence on the Feb 28 strike at the Minab girls' boarding school as "highly unusual" and "without recent precedent in published U.S. military investigations of incidents producing comparable civilian casualty figures." [1] The strike killed 168 people. Iranian human-rights documentation organizations, the United Nations Office of the High Commissioner for Human Rights, and Amnesty International have all independently estimated that approximately 110 of the dead were children; the figure has not been disputed by any U.S. official. [2] Friday is day three of the silence the paper has been counting since the named-officials letter became public Wednesday afternoon.

The five former officials are: Sarah Harrison, formerly an associate general counsel at the Pentagon for international affairs and the law of war; James W. Houck, a retired rear admiral and the former Navy Judge Advocate General; Larry Lewis, formerly a senior Pentagon civilian-casualty adviser and now at the Center for Naval Analyses; Sahr Muhammedally, formerly a director at the Center for Civilians in Conflict and a former Pentagon contracted civilian-harm reviewer; and Mary Wareham, the former U.S. Department of State arms-control adviser. [3] Their signatures sit, in the letter's hierarchy, at five separate professional registers — military legal, navy judge advocate, civilian-casualty technical, NGO-and-contracted, and arms-control. The letter is, in the letter's own framing, "not a partisan document. It is a document about the Pentagon's institutional obligations to itself."

The Department of Defense has, since the Feb 28 strike, said only that the incident "remains under investigation," that the investigating command is U.S. Central Command, and that no public timeline for the investigation's conclusion has been set. [4] The Pentagon press secretary, Sean Parnell, has — across roughly thirty regular briefings since Feb 28 — declined to answer questions about Minab on the basis that the investigation remains active. The standard response, as recorded in transcripts, runs: "I'm not going to get ahead of the CENTCOM investigation." [5] What the named-officials letter argues, in its central paragraph, is that nine weeks is — by the Pentagon's own historical practice — a long-enough silence to itself constitute a category of institutional response.

"In incidents involving civilian casualty figures of comparable scale," the letter reads, "the United States Department of Defense has, in the past quarter century, produced an interim public assessment within thirty to forty-five days of the incident. The Kunduz hospital airstrike of October 3, 2015 produced a public Pentagon Centcom investigation summary within forty-eight days. The MV-22 Osprey crash producing twenty-three U.S. service-member casualties in 1999 produced an interim public assessment within thirty-one days. The August 2021 Kabul airport drone strike, which killed ten Afghan civilians including seven children, produced a public Pentagon investigation conclusion within seventeen days. Nine weeks of silence on a strike that killed 168 people, including roughly 110 children, is — without further public-facing institutional explanation — highly unusual." [3]

The letter's institutional reference points are deliberately chosen to be recent, well-documented, and bipartisan. Kunduz was 2015, under Obama. The Kabul drone strike was 2021, under Biden. The 1999 Osprey crash was under Clinton. The institutional norm the letter describes is, in the letter's framing, not a partisan norm. The departure from it is what the letter asks the Senate Armed Services Committee to confirm or to disprove.

Hegseth's Thursday Senate Armed Services Committee testimony — his first public hearing on the broader Iran war and the second Senate appearance of his tenure — confronted the Minab question. Senator Chris Murphy of Connecticut, the committee's lead Democrat on civilian-casualty issues, read into the record a portion of the named-officials letter and asked the secretary to commit to an interim public assessment by May 15. Hegseth declined. The exchange, recorded in the committee's official transcript released Friday morning, included this line from the secretary: "I am not going to commit, on this hearing's clock, to an investigative output's clock." [6] Murphy's response — that "the institutional clock is the only one the families have" — was the line that carried in cable news Thursday evening. [7]

What the Hegseth testimony also confronted, in less-noted detail, is the hollowing-out of the Pentagon office created specifically to reduce civilian-casualty incidents. The Office of Civilian Casualties — established under the Carlin–Hicks 2022 directive in response to congressional pressure after the Kabul incident — was, according to a Defense News report Wednesday, reduced to four staff members in a March reorganization, down from a 2024 high of twenty-three. [8] The named-officials letter cites the office's reduction as relevant context. The Senate Armed Services Committee's lead Republican on the office's authorization, Roger Wicker, did not address the staffing changes in his Thursday remarks. The Civilian Casualty Office's deputy director, who is on detail from the Air Force JAG corps, declined to comment when reached Friday morning by phone. [8]

What Iran has said about Minab is the third register the silence operates against. Iran's Foreign Ministry has, in three separate statements since Feb 28, called the Minab strike a "blatant war crime" and demanded an international investigation under the Geneva Conventions' grave-breaches framework. [9] Amnesty International has, in a March 4 public letter to the U.N. Human Rights Council, called for "a full, independent, and impartial investigation into the U.S. strike that killed more than 100 children." [10] The U.N. Office of the High Commissioner for Human Rights has called for "accountability and full disclosure." None of these registers is unusual; what is unusual is that the Pentagon itself has produced none of the institutional response that, in the letter's framing, has historically accompanied incidents at this casualty scale.

The Senate Armed Services Committee's Friday letter to Hegseth, signed by Murphy, Wicker, and committee chair Jack Reed, requests an interim Pentagon assessment by May 30 and a full public report by July 15. [11] Hegseth's response — signed Friday afternoon — committed only to the assessment of the assessment process; the operative phrase in his letter is "we will continue to engage with the committee on the appropriate sequencing of the public-facing elements of the CENTCOM investigation." [11] The Senate's letter does not include enforcement language; the Pentagon's response does not include a date.

Day three. Five former officials. Hegseth's hearing in the record. The Senate's letter on the desk. The Civilian Casualty Office reduced to four. 168 dead. Approximately 110 of them children.

The Pentagon press briefing scheduled for next Tuesday is the next institutional clock the silence runs against. Whether it produces an answer, on Tuesday or on any of the following Tuesdays, is the question the named-officials letter has now made institutional.
