Joe Kent, a retired U.S. Army Special Forces officer who served as director of the National Counterterrorism Center, resigned on March 17 in protest of the U.S. war with Iran. In a letter to President Trump, Kent wrote that "Iran posed no imminent threat to our nation" and argued the conflict was launched due to "pressure from Israel and its powerful American lobby." He stated he could not "in good conscience support the ongoing war in Iran" or "send the next generation off to fight and die in a war that serves no benefit to the American people."

NBC News and CNN confirmed the resignation, while Fox News covered it prominently, noting the administration's swift pushback. White House Press Secretary Karoline Leavitt said Trump possessed "strong and compelling evidence that Iran was going to attack the United States first" and called Kent's accusation of Israeli influence "both insulting and laughable." House Speaker Mike Johnson said Kent was "clearly wrong" on the imminent threat assessment. Director of National Intelligence Tulsi Gabbard defended the administration's threat assessment.

The Daily Wire published a piece titled "Joe Kent Never Should Have Had This Job," arguing he used his position to undermine Trump and the war effort. The Washington Examiner reported that following the resignation, Senate Minority Leader Mitch McConnell and others accused Kent of antisemitism based on his characterization of Israeli influence. Kent — whose wife Shannon, a Navy intelligence officer, was killed in a 2019 ISIS bombing in Syria — is a well-known figure in MAGA circles and had previously been endorsed by Trump for a congressional race.

Days after the resignation, NBC News reported the FBI had opened an investigation into Kent for allegedly leaking classified information, with officials saying the probe began before he publicly announced his departure. Kent's case has become a flashpoint in a broader MAGA debate about the Iran war, with Tucker Carlson and other anti-interventionist conservatives treating his resignation as vindication of their opposition to the conflict. Trump dismissed Kent as "very weak on security."
