Introduction
In October 2023 the head of the United Nations and the head of the Red Cross jointly asked governments to write new international law on autonomous weapons by 2026. The text is short, and its wording differs in instructive ways from the policy of the US military.
This reading goes through the call, sets it beside the US Defense Department's directive, and asks what has happened as the deadline arrived.
Locating the Passage
The text is on the website of the International Committee of the Red Cross, free and listed in the References. Its full title is "Joint call by the United Nations Secretary-General and the President of the International Committee of the Red Cross for States to establish new prohibitions and restrictions on Autonomous Weapon Systems." It is dated October 5, 2023 and runs to about eleven short paragraphs. The paragraphs aren't numbered, so this reading identifies passages by quoting them. All quotations in the first three steps are from this text (Guterres and Spoljaric 2023).
The authors are António Guterres, Secretary-General of the United Nations, and Mirjana Spoljaric, president of the International Committee of the Red Cross, a humanitarian organization with a recognized role in the laws of war. Neither can make international law. The call is addressed to states because only states can negotiate a treaty.
Walking Through the Passage
Step 1: Read what the two leaders ask states to do, and by when
The opening sentence says the two are "calling on political leaders to urgently establish new international rules on autonomous weapon systems, to protect humanity."
The specific request comes later: "We call on world leaders to launch negotiations of a new legally binding instrument to set clear prohibitions and restrictions on autonomous weapon systems and to conclude such negotiations by 2026."
Three things are being asked: to start negotiating, to make the result "legally binding," which means a treaty and not a declaration, and to finish by 2026. That gave states a little over three years.
The call also says what it means by the term. It describes these as "weapon systems that select targets and apply force without human intervention."
Step 2: Identify the two kinds of rule requested
The title names both: "prohibitions and restrictions." They're different instruments. A prohibition bans a category outright. A restriction allows a category under conditions.
On prohibitions, the call says: "This means prohibiting autonomous weapon systems which function in such a way that their effects cannot be predicted." It gives an example: "allowing autonomous weapons to be controlled by machine learning algorithms – fundamentally unpredictable software which writes itself – is an unacceptably dangerous proposition."
That sentence makes a strong technical claim. Machine learning systems are built by training on examples, and their behavior in new situations can't be fully predicted from their design. The call treats that property as disqualifying for a weapon. Those who favor such systems would answer that testing can establish how reliably a system behaves within set conditions.
The call also draws a line around targeting people: "The autonomous targeting of humans by machines is a moral line that we must not cross."
On restrictions, it says that "clear restrictions are needed for all other types of autonomous weapons." These include "limiting where, when and for how long they are used, the types of targets they strike and the scale of force used, as well as ensuring the ability for effective human supervision, and timely intervention and deactivation."
Step 3: Read the reasons given
The call says that autonomous weapon systems "pose serious humanitarian, legal, ethical and security concerns." Each adjective points to a separate argument.
- Humanitarian. A weapon that chooses its own targets may strike civilians.
- Legal. Those laws assume a human who can be held responsible. If a machine selects the target, it's unclear who answers for an unlawful strike.
- Ethical. The call states: "Human control must be retained in life and death decisions."
- Security. The call warns that by "creating a perception of reduced risk to military forces and to civilians, they may lower the threshold for engaging in conflicts, inadvertently escalating violence."
The ethical reason is of a different kind. The other three are claims about consequences, which better technology could in principle answer. The ethical reason says that some decisions shouldn't be delegated however well the machine performs.
Step 4: Set the call beside the US directive and mark the difference
The US Department of Defense states its policy this way: "Autonomous and semi-autonomous weapon systems will be designed to allow commanders and operators to exercise appropriate levels of human judgment over the use of force" (US Department of Defense 2023, sec. 1.2).
Compare the key phrases. The call says "human control must be retained." The directive says "appropriate levels of human judgment."
Control and judgment aren't the same. Judgment can be exercised before a weapon is launched: a commander decides that conditions are right, sets the area and the kind of target, and activates the system. After that the machine may act with nobody able to stop it, and the standard is still met. Control suggests a person who can supervise and intervene while the system operates, which is what the call's "timely intervention and deactivation" asks for.
"Appropriate" matters too. It makes the required level depend on the situation, as judged by the military itself.
The two also differ in kind. The directive is one country's internal policy, which that country can change. The call asks for limits fixed in law that binds every state that joins.
Step 5: Note that the deadline has arrived and say what the UN votes show
The call's deadline was 2026. The UN General Assembly's votes show how far states have moved.
In December 2024 the General Assembly adopted a resolution on these weapons by 166 votes to 3, with 15 abstentions (United Nations 2024). In 2025 it adopted another by 164 votes to 6, with 7 abstentions. The United States was among the six voting against. That resolution speaks of completing the elements of an instrument "with a view to future negotiations" (United Nations 2025).
So a large majority of states supports continued work. The phrase "future negotiations" indicates that formal treaty negotiations hadn't begun in 2025. As of October 2026 no source checked for this reading shows a treaty. Several states with advanced militaries voted against or abstained, and a treaty they don't join wouldn't bind them.
Key Considerations
A call is an appeal. It isn't an agreement, and no state signed it. Reports that "the UN called for a ban" are accurate about the Secretary-General and say nothing about what member states have decided.
A common mistake is to treat "human judgment" and "human control" as the same standard. News reports often use the phrases interchangeably. The difference is the substance of the dispute. A government can honestly say it requires human judgment over the use of force while fielding weapons that select their own targets after launch.
The call also asks for less than a total ban. It would prohibit two categories and restrict the rest.
Summary
The joint call asks states for a binding treaty that prohibits some autonomous weapons and restricts the others, and the US directive sets an internal standard that permits them under review. The result of the reading is this comparison.
| The joint call (2023) | The US directive (2023) |
|---|
| What it is | An appeal to states by two leaders | One country's internal policy |
| Key standard | "Human control must be retained in life and death decisions" | "Appropriate levels of human judgment over the use of force" |
| Unpredictable systems | Prohibit | Not prohibited as a category; systems are tested and reviewed |
| Targeting people | "A moral line that we must not cross" | Not prohibited as a category |
| Other autonomous weapons | Restrict by place, time, target, and scale, with human supervision and the ability to deactivate | Permitted after approval by senior officials |
| Legal form sought | A binding treaty, concluded by 2026 | None; the policy can be revised by the department |
