White House Deputy Chief of Staff Stephen Miller has issued a stern warning to Iran amid stalled negotiations between Washington and Tehran. Speaking to Fox News, Miller said that Iran’s current leadership now faces a final deadline from the United States after talks failed to make progress. He stated that Tehran must choose between signing an agreement acceptable to Washington or facing a military response unlike anything seen in modern history.

The warning comes as diplomatic discussions between the two nations remain deadlocked, with no breakthrough reported. Miller emphasized that the Iranian administration has only two options left—either comply with the terms favored by the United States or face severe military consequences. His remarks underscore the growing tension surrounding the unresolved negotiations.

The statement signals a hardening U.S. stance toward Iran, suggesting that Washington may be preparing to escalate pressure if Tehran refuses to meet its conditions.
