During an April 13 broadcast, Fox News host Tucker Carlson cited a tranche of recently leaked U.S. intelligence documents as evidence that “Ukraine is in fact losing the war” against Russia. Carlson said that “seven Ukrainians are being killed for every Russian,” a claim that receives no support from the leaked documents, the authenticity of which has been confirmed by U.S. officials.

Carlson did not provide a citation for his claim regarding the ratio of Ukrainian to Russian dead, but the numbers he cited are explicitly contradicted by the leaked intelligence documents he referenced elsewhere in his April 13 broadcast. According to reporting by the New York Times, the leaked documents estimate that up to 43,000 Russians and 17,500 Ukrainians have been killed in action during the war. These numbers have been corroborated by other sources including Reuters, the Wall Street Journal, CNN, and the Financial Times. Here are the broader casualty estimates from the documents as reported by Jake Epstein of Business Insider:

One document in particular suggests that Russia has suffered between 189,500 and 223,000 casualties, including between 35,500 and 43,000 soldiers killed in action and between 154,000 and 180,000 troops wounded.

Ukraine, by contrast, has suffered between 124,500 and 131,000 casualties, including between 15,500 and 17,500 soldiers killed in action and between 109,000 and 113,500 troops wounded.
