AI and Autonomous Weapons: Who Pulls the Trigger When the Machine Decides?

The core US policy is DoD Directive 3000.09, "Autonomy in Weapon Systems," first issued in November 2012 and updated in January 2023. Its central line: "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." It does not ban autonomous target selection outright, and it does not define "appropriate" with a fixed rule that applies the same way in every scenario.

The Congressional Research Service's public defense primer on the policy notes that human-supervised autonomous weapon systems may be permitted to select and engage targets in specific contexts — such as intercepting inbound attacks — while a categorical exception is written in for selecting human beings as targets. The Pentagon has signaled it intends to revisit the directive again, but as of this file's writing, the 2023 version remains the governing US standard.

In April 2024, the Israeli outlets +972 Magazine and Local Call published a joint investigation, based on interviews with multiple named and anonymous Israeli intelligence sources, describing an AI system called "Lavender" used by the IDF to help identify suspected Hamas or Palestinian Islamic Jihad operatives, alongside a related system called "The Gospel" used to help select physical strike sites. The investigation's most widely reported claim is that Lavender flagged tens of thousands of names as potential targets, and that human review of each flagged name in practice took on the order of twenty seconds before approval.

The IDF's public response called elements of the reporting "baseless in fact" and described a human-controlled targeting process in which the AI systems provide a starting point for analysts rather than a final decision. Both the investigation's sourcing and the IDF's rebuttal are part of the public record; this file treats the specific twenty-second figure and the scale of flagged names as reported claims from a named investigative outlet, not independently verified facts, while treating the existence of the Lavender and Gospel systems themselves — which the IDF has not denied operating — as established.

On November 6, 2025, the UN General Assembly adopted a resolution on lethal autonomous weapons systems by a vote of 156 in favor, five against and eight abstaining. The resolution expresses concern about an emerging arms race, the risk of escalation and proliferation to non-state actors, and calls for a "comprehensive and inclusive multilateral approach." It does not create a binding legal framework and does not mandate formal treaty negotiations — a group of governmental experts has been meeting on the issue for years without producing one.
