(NEW YORK) — President Donald Trump’s decision to carry out strikes on Iran has further exposed a fracture among some of the president’s fiercest supporters inside MAGA world — one that many supporters say will only widen with every week the conflict continues.

Since the first strike last week, Trump’s actions in Iran have faced stark criticism from some of the most popular voices in MAGA media who helped boost his 2024 campaign, ranging from longtime adviser Steve Bannon to more recent converts like conservative media personalities Tucker Carlson and Megyn Kelly.

Prominent figures within the movement say the strikes have already tested the limits of their support, according to interviews with over a dozen leading voices inside President Trump’s MAGA coalition, who point to shifting justifications, no clear endgame, the specter of another Middle East forever war, and the use of American resources overseas versus at home as concerns that they warn will only deepen and carry a steeper political price the longer the operation lasts.

“He has a maximum of a month,” Natalie Winters, White House correspondent for Bannon’s War Room program, told ABC News. “After that people will start viewing this as just another dragged-out conflict.”

Since the strikes last week, the president and Trump officials have offered a creeping timeline for how long the operation in Iran could last, with Trump initially stating the operation was “ahead of schedule” and that the war could last “four weeks — or less.”

But in recent days the administration has signaled the potential for a much longer conflict, with Secretary of Defense Pete Hegseth stating this week that the operation had “only just begun.”

“We have only just begun to fight and fight decisively,” Hegseth told reporters. “Iran is hoping that we cannot sustain this, which is a really bad miscalculation.”

On Wednesday, Hegseth said the war could go as long as eight weeks or beyond, the longest timeline the Trump administration has offered thus far.

For a base filled with influential — and loud — voices who say they supported the president in large part because of his promise to avoid not just foreign intervention but “forever wars,” the administration’s shifting timeline has become a ticking clock.
