Defense Secretary Pete Hegseth, who served as the administration's most visible champion of military strikes against Iran, has gone largely silent on the subject since President Trump signed a memorandum of understanding with Tehran on June 17. The shift has left Vice President JD Vance as the public face of a diplomatic track that remains fragile and, by several accounts, stuck.
The contrast is sharp. During 39 days of U.S. and Israeli strikes under Operation Epic Fury, from February 28 through April 8, Hegseth and Joint Chiefs Chair Dan Caine briefed reporters regularly. Trump himself said in March that Hegseth was "the first one" to speak up in favor of military action, while Vance was "notably less enthusiastic about the war."
Now the roles have reversed. The Hill reported that Hegseth has offered almost no public commentary on Iran since the MOU was signed, and the Pentagon has returned to its prewar practice of dispensing with routine press briefings on the conflict. Hegseth's office did not respond to a request for comment.
The June 17 agreement gives Washington and Tehran 60 days to broker a final peace deal. That deal is supposed to resolve the status of Iran's enriched uranium and free up billions of dollars in frozen Iranian assets. Qatar and Pakistan are mediating.
But the talks have already hit a wall. Iran's control over the Strait of Hormuz, one of the world's most critical shipping chokepoints, remains a sticking point, and no public progress has been announced on the nuclear provisions.
Trump told reporters last week that Iran is cooperating: "They're agreeing to everything that I want, and they have to. Otherwise, we just go back and do what we have to do." Two U.S. aircraft carrier strike groups remain deployed in the Middle East, and the president has kept the military option explicitly on the table.
The Wall Street Journal reported this week that Hegseth and Caine held multiple conversations with Trump about additional strikes on Iran, but the president chose to continue negotiations instead.
The Defense Secretary's most recent substantive comments on the conflict came before he departed for a NATO meeting in Brussels last month. He warned that the military stands ready to resume operations if Iran fails to follow through:
"We will be prepared to recommence if, underneath the timeline of these talks, Iran does not do what it says it's going to do, which is give up nuclear weapons, give up nuclear ambitions, give away their nuclear material, close nuclear facilities. Then the War Department is here and prepared to restart if we need to. We prefer not to, but we are prepared."
On the day the MOU was signed, Hegseth called Trump's deal "far superior" to the Obama administration's 2015 Joint Comprehensive Plan of Action, adding that the U.S. would "make sure the military option is there."
Since then, near-silence, at least on Iran. Hegseth has instead turned his public attention to Pentagon spending fights, including increasingly frequent trips to Capitol Hill to shore up support for Trump's $1.5 trillion defense funding request and approximately $80 billion in supplemental spending to backfill munitions used during the Iran campaign.
That mammoth budget ask has not gone down well with lawmakers, and it represents the kind of unglamorous legislative work that tends to happen far from cameras.
Several defense analysts offered The Hill competing explanations for Hegseth's retreat from the Iran spotlight. The most sympathetic interpretation: a Defense Secretary's job during active diplomacy is to stay in his lane.
Anthony Constantini, policy director at the Bull Moose Project, a conservative advocacy group, cast the dynamic in straightforward terms. "He is not the guy who is leading the negotiations," Constantini said, describing Hegseth's wartime role as the "bad cop" and noting it would be "odd" if he were "constantly talking" about the agreement now.
That reading aligns with common sense. A secretary of defense who spent weeks projecting force is not the natural messenger for a diplomatic pause. And if the president wants the vice president out front on talks, the Pentagon chief follows orders.
Jason Dempsey, an adjunct senior fellow at the Center for a New American Security and a veteran of more than two decades as an Army infantry officer, offered a blunter assessment. He told The Hill that Hegseth's early vocal support for the war reflected "post-Venezuela hubris that led the administration into this ill-conceived and poorly executed war with Iran." Dempsey added:
"His recent attempts to avoid being the face of the conflict may be the smartest thing he has done thus far."
Dempsey argued that Hegseth is reverting to a safer playbook: "Throw red meat to the MAGA faithful every few weeks in a way that keeps him in the headlines, rescinding the flu vaccine mandate, purging religious classifications, et cetera. Issues that don't risk him going sideways with Trump."
Those domestic Pentagon moves have generated their own friction. Hegseth has vowed to take legal battles over transgender troop policies to the Supreme Court, and he has drawn pointed criticism from members of his own party on Capitol Hill.
Yvonne Chiu, a professor of strategy and policy at the U.S. Naval War College and Jeane Kirkpatrick Visiting Fellow at the American Enterprise Institute, was less forgiving. She told The Hill that Hegseth gravitates toward spectacle over substance:
"He's really interested in either the kind of very showy kinetic actions, like bombings, daring flight missions and special operations and that stuff, or he's interested in these internal culture wars. But he's not interested in the hard work of all of these other things that secretary of Defense ought to care about, like force design and how to keep the peace."
On the broader administration silence, Chiu added: "I think because they realize that it's not a great deal, doesn't mean nothing good can come of it, but it's not a good deal, and so I think the less attention they draw to it, the better, is the general attitude about it."
Allison McManus, managing director at the left-leaning Center for American Progress, pointed to the absence of good news as the simplest explanation. "Whether that's Hegseth or Rubio or Witkoff or Trump himself, there's not much that's been positive to report," she said. McManus also argued that Hegseth's public posture reflects Trump's wishes: "I think if Trump wanted Hegseth to be doing daily briefings, whether or not Hegseth agreed with what's in the MOU, he would be doing the daily briefings."
Hegseth has also faced sharp criticism from retiring Republican Senator Tillis, who publicly compared the Defense Secretary's missteps unfavorably to those of other Trump appointees, a sign that internal GOP frustration extends beyond policy disagreements.
While Iran went unmentioned, Hegseth did surface publicly on Thursday at Meridian Hill Park in Washington, D.C., for a D.C. Safe and Beautiful Task Force event. Roughly three dozen protesters blared sirens nearby. Hegseth spoke for nearly five minutes, praising National Guard troops who have been deployed in the capital for almost a year.
He addressed the protesters directly: "This background noise this morning is perfect; it's the sound of ingrates, of ingratitude, of people who are so blinded by ideology they can't see law and order and common sense in front of them."
He also defended the Guard deployment in nonpartisan terms: "There's nothing ideological about this group. There's nothing political about this exercise. Law and order is something all Americans deserve, Black, white, rich, poor, man or woman, from D.C. or far-flung places in this country."
The appearance fit a pattern. Hegseth has drawn conservative criticism over messaging choices even from allies, and his public schedule increasingly tilts toward domestic law-enforcement themes and Pentagon culture fights rather than the Iran portfolio that once dominated his briefings.
The MOU's 60-day window for a final deal means the deadline falls in mid-August. If Iran's enriched uranium, its frozen assets, and the Strait of Hormuz dispute remain unresolved, the administration will face a choice: extend talks, accept a partial agreement, or restart military operations that consumed more than 13,000 strikes over 39 days and left the Pentagon requesting $80 billion to restock.
None of those options are simple, and none will be made easier by a Defense Secretary who has clashed with lawmakers over classified briefing disclosures and faces questions about whether his public profile serves the mission or his own brand.
For now, the administration's position is that diplomacy is working and the military option remains live. Whether that holds depends on Tehran, and on whether the officials responsible for American defense are willing to do the quiet, grinding work that peace demands, not just the loud work that war allows.
Being the frontman for a bombing campaign is easy compared to being accountable for what comes after. The next few weeks will test whether this administration, and its Defense Secretary, are ready for that harder job.
