Iran signs the Tehran declaration with Britain, France and Germany on nuclear work

On 21 October 2003 Iran signed a declaration in Tehran with the foreign ministers of Britain, France and Germany to suspend uranium enrichment and sign an Additional Protocol. Neighbouring Paris 2004 is a later EU3 text. In the causal graph this event strengthens Energy Security, a driver that strengthens Poverty headcount ratio at $3.00 a day (2021 PPP) (% of population) — a worsening welfare path.

Read the full account

On 21 October 2003 Iran signed a declaration in Tehran with the foreign ministers of Britain, France and Germany to suspend uranium enrichment and sign an Additional Protocol. Khamenei was Leader.

Context

Khatami was president. Neighbouring Paris 2004 is a later EU3 text. He did not sit as an IAEA inspector.

Paris 15 November 2004 is neighbouring. JCPOA is a different decade.

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

International Atomic Energy Agency carries the official instrument or communique. Reuters records the same dated act independently.

Established: 21 October 2003 Tehran declaration, independently reported.

Not established: that enrichment never resumed, or a unique later weapon coefficient of zero.

Khatami’s government signed. The EU3 sat. The IAEA inspected.. A later repeal, court stay, or successor order would be a different Fact with a different date. That pair identifies Iran signs the Tehran declaration with Britain, France and Germany on nuclear work, not a later speech about Iran signs the Tehran declaration with Britain, France and Germany on nuclear work.

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 He allowed the pause. Khatami’s government signed. The EU3 sat. The IAEA inspected. That limit is the alternative to treating office-holding as authorship of every later series.
