Retired four-star General Jack Keane argued that continued negotiations with Iran have reached a dead end, contending that Tehran is merely buying time and that renewed military action offers the most effective path forward.

Speaking on Fox News on Friday, the former Army vice chief of staff and current chairman of the Institute for the Study of War criticized the past eight weeks of talks, saying Iran’s leadership has no genuine intention of reaching an agreement.

“We have to accept the reality that’s just not going to happen,” Keane said on Fox News. “They have one motive: Stretch out negotiations as much as possible, get as close to the political situation in terms of midterm elections, and there will be less likelihood that President Trump would ever pull the trigger and go back to military operations. I believe that is their unstated strategy.”

Keane also expressed skepticism about any future agreement with Tehran, warning that even a signed deal would fail to produce lasting results and could strengthen the regime.

“We can’t throw them a financial lifeline … because then they’ll systematically reverse everything,” he said. “They’ve always cheated in the past, and they’ll cheat in the future.”

While praising President Trump’s decision to begin military operations against Iran on February 28, Keane maintained that the campaign was halted before its objectives were fully achieved.

“Look, in close to 50 years, only one president has taken consequential action against Iran and their predator behavior — and that’s President Trump,” Keane said. “Five weeks of Epic Fury and a naval blockade devastated this regime militarily and economically. They’re down, but they’re not out.”

According to Keane, U.S. and Israeli forces were only a short time away from completing critical objectives when combat operations were suspended. He added that the pause has allowed Iran time to regroup, but has also provided the United States with additional intelligence and a larger target set.

“If we go back to military operations — and I believe that’s the preferred option — we should return to full combat operations,” Keane said.

Keane dismissed suggestions that a limited military response could effectively deter Iran, arguing that Tehran would retaliate regardless of the scale of an attack.

“Iran is going to retaliate regardless of whether you go small or go big. Let’s go big,” he said. “Take down as much of their capability as we possibly can and get these guys as close to collapse as military operations can possibly achieve.”

“And then with economic pressure, we can put this regime truly on the path to collapse.”

His comments came as some U.S. military officials reportedly told The New York Post that a broader strategy targeting Iran’s most influential hardline figures may ultimately be required. Those officials reportedly questioned whether additional conventional military strikes alone would be enough to force meaningful policy changes from the regime.

The sources pointed to the deeply entrenched ideology of Iran’s hardline leadership and the Islamic Revolutionary Guard Corps, whose loyalty is centered on preserving the Islamic Revolution rather than addressing the broader interests of the Iranian population.

One source indicated that such a strategy could involve Israeli participation in targeted leadership strikes, while American forces would focus on remaining weapons infrastructure, launch sites, and other strategic targets near the Strait of Hormuz.

Meanwhile, Israeli officials have reportedly expressed support for renewed military operations. Prime Minister Binyomin Netanyahu publicly reiterated his support for regime change in Iran during an interview with CNBC on Thursday.

“We’ve wreaked a lot of damage to this regime, not destroyed it, but weakened it. We see the cracks propagating in the regime,” he said. “We have to help the Iranian people to bring down this regime, and that hasn’t changed.”
