Palantir CEO Alex Karp proclaimed on a panel in 2024 that "technology should be able to reduce drastically the amount of collateral damage, civilian deaths." Former Google CEO Eric Schmidt and former Deputy Director of the CIA David Cohen agreed.

Proponents of artificial intelligence use in the military have long made some version of this argument — that the military's adoption of AI will lead to a reduction in civilian harm.

Rep. Jim McGovern (D-Mass.) summarized the pitch during a congressional hearing about AI use in the military on Wednesday. "Our government has argued that AI could improve assessments of the likely effects of military operations and reduce the risk of civilian casualties," McGovern said. "That's the pitch that we're getting. I mean, does everybody agree with that?"

The question is no longer theoretical, as the U.S. military is already deploying AI. The Pentagon struck 13,000 targets in just the first 38 days of war, aided by Palantir's Maven Smart System to identify targets and choose weapons used for attacks.

But experts at the hearing, hosted by the Tom Lantos Human Rights Commission, said the argument that AI reduces civilian harm simply isn't supported by the facts on the ground, pointing to Iran, Ukraine, Yemen, and Gaza as evidence.

"I disagree with that," said Steven Feldstein, a senior fellow in the Democracy, Conflict, and Governance Program at the Carnegie Endowment for International Peace. While some tout targeting accuracy within AI systems being up to 90%, Feldstein says the real number may be closer to 50%.

Deborah Brown, deputy director of technology, rights & investigations at Human Rights Watch wasn't convinced by the argument either. "Whether it's Israel in Gaza, whether it's Iran, the evidence doesn't suggest that this is limiting the harm because of the high level of civilians dead."

Lawmakers have raised questions over whether AI played a role in the February 28 attack on a girls' elementary school in Minab, Iran, which killed over 170 people. Palantir's Shyam Sankar made the compassionate case for the military using Maven when asked about his company's alleged role in the attack. "It's a tragedy for those girls for sure," Sankar said. "The thing I would say is that in the history of warfare, technology has always reduced collateral damage."

But Feldstein explained that "even if there is more accuracy, because the number of targets is so much vaster, the ultimate number of civilians harmed is likely far higher as well."

For instance, the Israel Defense Forces claims to have a 90% accuracy rate with Lavender, its AI-targeting system used in Gaza. But Amanda Klasing, national director of government relations and advocacy at Amnesty International USA, pointed out that accuracy doesn't matter when proportionality is "blown out of the water," such as when a 2,000-pound bomb is dropped on a residential building.
