“No Quarter” Rhetoric Risks Violating International Law

In a March 13 Pentagon press briefing, U.S. Defense Secretary Pete Hegseth made headlines with a stark declaration about the ongoing conflict involving the United States, Israel, and Iran. Statements like “no quarter, no mercy for our enemies” have sparked alarm among international law scholars and civil liberties advocates because of what the phrase “no quarter” actually means in the laws of war¹.

For much of modern history, “no quarter” has been understood in military contexts to mean an order that enemy combatants should not be taken prisoner and must be killed even if they are incapacitated or have surrendered². Under established international humanitarian law — the body of legal rules governing conduct in war — issuing such a directive is more than aggressive rhetoric; it is expressly prohibited and considered a war crime¹ ².

The prohibition against declaring that “no quarter will be given” dates back at least to the 1907 Hague Convention, an early 20th‑century treaty to which the United States is a party. Article 23(d) of that treaty states it is *“especially forbidden to declare that no quarter will be given.”*³ Despite the absence of a recent explicit operational order, Hegseth’s phrasing has been widely reported as implying exactly this kind of directive⁶.

International humanitarian law — codified not only in the Hague Conventions but also in subsequent treaties and customary war law — recognizes a fundamental obligation to protect persons who are not actively participating in hostilities. This includes soldiers who are hors de combat (out of the fight due to surrender or incapacitation), non‑combatants, and civilians². Legal commentaries note that ordering the denial of quarter constitutes a grave breach of these protections¹ ³.

Moreover, modern legal frameworks like the Rome Statute of the International Criminal Court clearly list “declaring that no quarter will be given” as a war crime in both international and non‑international armed conflicts¹. U.S. military doctrine — reflected in the Department of Defense Law of War Manual — aligns with this prohibition, reinforcing that such orders are forbidden under U.S. and international law¹ ⁵.

Critics argue that even if such statements are not operational war orders, public rhetoric from high‑ranking defense officials matters because it can shape the expectations and conduct of forces in the field and influence public perceptions of acceptable wartime behavior⁶. A bipartisan range of observers, including Senator Mark Kelly (a military veteran), has publicly condemned the use of “no quarter” language and stressed that it contradicts longstanding legal and ethical norms⁶.

The stakes are high. While the United States is not a party to the International Criminal Court’s jurisdiction, the principles enshrined in the Hague and Geneva Conventions represent binding norms of customary international law accepted by most nations, including the U.S.¹ In addition, U.S. statutes like the War Crimes Act incorporate these principles into domestic law, making certain violations punishable under U.S. criminal law¹.

In times of international conflict, leaders must balance military objectives with global legal and ethical standards. Language that suggests abandonment of fundamental protections under the laws of war undermines both American legal commitments and broader efforts to uphold humanitarian norms in armed conflict.
