    November 2026: Rated partly true rather than confirmed: records show the makers knew dioxin could injure workers, but the Second Circuit found no evidence they knew of a long-term cancer risk or withheld information that would have changed the military's decision, and the Pentagon halted Agent Orange use in April 1970. Corrected several dates and figures and added 2024-26 developments.
