Read the full account
In September 2023 the United States and Iran completed a prisoner exchange that freed several US nationals from Iranian detention and Iranians from US cases, with frozen funds moved under a Qatar arrangement. Khamenei was Leader.
Context
Biden’s administration sat. Neighbouring JCPOA revival talks had stalled. He did not sit as a US judge.
JCPOA reductions are neighbouring. Pezeshkian’s later Islamabad MoU is 2026.
The Supreme Leader of Iran is commander-in-chief and the highest constitutional authority. He does not write a US presidential strike order, an IAEA Board resolution, or a Hamas military plan. Presidents, the IRGC, and the Guardian Council implement and share specific files.

What the sources establish
U.S. Department of State carries the official instrument or communique. Reuters records the same dated act independently.
Established: September 2023 US–Iran prisoner exchange, independently reported.
Not established: that all dual-national cases ended, or a unique later JCPOA revival from the tarmac.
The US released its side. Qatar hosted funds.. A later repeal, court stay, or successor order would be a different Fact with a different date. That pair identifies The United States and Iran complete a prisoner exchange, not a later speech about The United States and Iran complete a prisoner exchange.
Co-authors and later implementers named in Context remain on the file. If a later repeal, stay, or successor instrument exists, it needs its own date and its own row. The contribution described on this Person row is limited to His system held and released the Iranian-side detainees. The US released its side. Qatar hosted funds. That limit is the alternative to treating office-holding as authorship of every later series.
