Claim: The US military is secretly using depleted uranium munitions in Iran

The claim that the US military is secretly using depleted uranium munitions in Iran is false. Official sources, including Iran's Nuclear Safety Center and various military reports, indicate no evidence of such use in recent conflicts. While there is speculation about the use of depleted uranium, particularly in past conflicts, current investigations have not substantiated these claims. Alternative sources may suggest otherwise, but they lack credible evidence to support their assertions. The models diverge sharply — treat this as higher-uncertainty. Perplexity comes in highest (50%), while Gemini is lowest (5%). Gemini expresses higher confidence than OpenAI on this claim. Some sources speculate about the potential use of depleted uranium munitions by the US in Iran, citing marginal evidence. However, this speculation does not provide concrete proof and is largely based on conjecture rather than verified reports. The lack of clear evidence from credible sources significantly undermines the validity of these claims, leading to a conclusion that the assertion of secretive military actions involving depleted uranium is unfounded.
