What the Evidence Shows
What is established
Majid Shakeri, identified as a senior adviser to Iran’s parliament speaker, said, “Trump will not reach an agreement with us. We will accompany him until his term ends,” with the term’s end identified as January 20, 2029.
A report characterized Iranian officials’ public position as ruling out future diplomatic negotiations with the Trump administration.
Context and caveats
The reported statement came from a senior parliamentary adviser rather than an identified Foreign Ministry announcement or signed decree, so it supports what an Iranian official said but does not by itself establish a formal executive policy.
The available evidence establishes the reported statement and its stated timeline, while leaving the breadth of its formal policy status qualified.
Whether the adviser’s statement represented a formally adopted Iranian government policy is not established by the approved evidence.
