Donald Trump Jr. had a simple vision for his father’s foreign policy during the 2024 presidential campaign: If elected, Donald Trump was going to keep America out of another war in the Middle East.
“Remember when they said Trump would get us into a full-blown war with Iran?” he wrote on X that April, as Iran launched a barrage of missiles and drones toward Israel. “Times like these should make us all realize how lucky we were to have Trump, his strength and his resolve.”
Two and a half years later, the president has enmeshed the United States in a full-blown war with Iran—and Trump Jr. isn’t happy about it.
Trump Jr. has repeatedly voiced his opposition to the ongoing Iran war in private conversations, two people who have spoken directly with him about the conflict told us. The president’s son, these people said, opposed the war from its outset and made his opposition known to his father. He has long been skeptical of foreign intervention, these people told us, and believed the U.S. should not enter another Middle East war. Trump Jr. was also especially close to Charlie Kirk, the late conservative activist, who had broken with the Trump administration to oppose the war in Iran.
“Don has kept his views on the subject private, as he would never publicly break with his dad on an issue like this, but I can’t imagine anyone who knows Don would be surprised by his personal views on the subject,” a person close to the president’s son told us. A spokesman for Trump Jr. declined to comment. The White House didn’t respond to questions about Trump Jr.’s position on the war, and an official said in a statement, “Iran has been decimated, and one way or the other, the conflict in Iran will be over very soon.”
The White House’s decision to ally with Israel against Tehran has exposed a deepening rift within MAGA—not just over Iran, but also over what “America First” actually means. The divide pits nationalists who see foreign wars as a betrayal of domestic priorities against hawks who argue that American power must be wielded more aggressively against its adversaries. For years, the two camps coexisted under Trump’s promise of strength without the cost of another major war. Iran has made that balancing act harder to sustain. “Don Jr. is the most MAGA of them all,” one of the people who spoke with him about his opposition to the Iran war told us.
Even within the administration, some of the president’s closest advisers, including Vice President Vance, have voiced private opposition to the war as they deliberated whether to join Israel in its military campaign. Others, including CIA Director John Ratcliffe and Secretary of State Marco Rubio, were skeptical of Israeli Prime Minister Benjamin Netanyahu’s initial pitch in February that a regime-change operation—particularly one conducted from the air—was remotely realistic.
The political costs are mounting. A Pew Research Center survey conducted over the past month found that 65 percent of Americans disapproved of Trump’s handling of the Iran operation, compared with 33 percent who approved. Republican approval fell from 69 percent in March to 63 percent. Nearly half of Americans expected the conflict to drag on for more than a year—far beyond the administration’s initial estimate of about four to six weeks.

The economic consequences have sharpened the political fallout. Rising gas prices, driven by disruptions to the energy markets, are squeezing already strained household budgets. The midterm elections will test whether Republicans can defend a war that many voters oppose, while convincing those same voters that the administration is focused on their economic concerns. Republican candidates have been forced to defend a war with immense costs and an uncertain conclusion—one that the president initiated without congressional approval.
Trump Jr.’s private opposition offers yet another reminder that doubts about the war are not confined to the president’s critics or the fringes of the Republican Party. It also points to a deeper sentiment within the president’s base that he has betrayed key campaign promises: to avoid foreign wars and to make life more affordable for the average American.
