“Your calculations failed, your assumptions collapsed, and your strategic misjudgments became painfully evident,” he wrote.

“The American people have now sent you a clear message,” Baqaei continued. “Yet, if you continue to disregard reality, dismiss the lessons of history, and persist in this dangerous course, the consequences of this grave miscalculation will extend far beyond what you have already witnessed.”

The sweeping Republican defeat has sharpened divisions over the Iran War.

Some lawmakers reportedly want to impeach Defense Secretary Pete Hegseth, who was an early advocate for the war. Rep. Thomas Massie (R, Ky.) told CNN that he intends to force a vote when Congress returns next week on his effort to impeach Hegseth. Massie has been a vocal intraparty critic of Trump and his Administration and lost his GOP primary race in May.

“There are Republicans who would support impeaching Hegseth who might not support doing it to Trump,” Rep. Adam Smith, the top Democrat on the House Armed Services Committee, told TIME last week.
