Iran builds Gulf security deals with China and Russia, bypassing US

Fact-check index: 58/100 — The NZZ claim is accurately and well-cited, but the two Middle East Eye claims cannot be verified since only headlines/URLs were provided as source material, not article text.

• Iran is building a Gulf security order without Washington, seeking guarantees from neighbors and backing from China and Russia; all parties see no role for the US — Directly matches the NZZ summary: 'Die Islamische Republik sucht mit einem Mal Sicherheit mit ihren Nachbarn am Golf und die Unterstützung durch China und Russland. Alle vereint, dass sie keine Rolle mehr für die Amerikaner sehen.' Properly cited.
• Tehran told Moscow that talks with Washington are worthless without concrete guarantees, since past negotiations collapsed into conflict — Headline 'Iran tells Russia talks with US without guarantees won't end conflict' supports the general gist, but only the headline/URL is given, not article text, so the specific detail about past negotiations collapsing into conflict is not verifiable from the provided source material.
• Mohsen Rezaei told Washington it had 'lost war and election' and warned of a 'devastating response' to any new strike — Headline 'You lost war and election': Iran's Rezaei warns US of 'devastating response' matches the quoted phrases, but no article body was provided to confirm attribution to Rezaei specifically or the 'new strike' context.
• A Gulf realignment toward Beijing and Moscow would loosen US leverage over energy routes and major-power diplomacy, leaving Trump sidelined — This is the article's own analytical framing/interpretation ('Why it matters'), not a claim directly sourced to any cited material.
