The same artificial-intelligence model that can help you draft a marketing email or a quick dinner recipe has also been used to attack Iran. US Central Command used Anthropic's Claude AI for "intelligence assessments, target identification and simulating battle scenarios" during the strikes on the country, according to a report in the Wall Street Journal.

Hours earlier, US President Donald Trump had ordered federal agencies to stop using Claude after a dispute with its maker, but the tool was so deeply baked into the Pentagon's systems that it would take months to untangle in favor of a more compliant rival. It was used, too, in the January operation that led to the capture of Nicolas Maduro.
