Iran sent its response to the latest US proposal to end the Iran war via Pakistani mediators on Sunday, but President Trump quickly rejected it as “TOTALLY UNACCEPTABLE!” in a social media post, causing a setback to diplomatic efforts to resolve the standoff in the Persian Gulf.

Citing a source, Tasnim News Agency said, “Trump’s reaction is of no importance. No one in Iran is working on formulating a plan to satisfy the American president.”

The statement highlights the widening gap between Washington and Tehran.

The US has stressed that any long-term agreement must address Iran’s nuclear programme, missile capabilities, and role in regional waterways.

Iran, in turn, has maintained that sanctions relief and formal recognition of its maritime rights must take precedence.

Trump’s rejection of the Iranian response included no details.

In an earlier post, he accused Tehran of “playing games” with the United States for nearly 50 years, adding: “They will be laughing no longer!”
