Chairman of the Joint Chiefs Gen Dan Caine has privately warned senior Trump advisers that the United States must seek an off‑ramp from the war with Iran, cautioning that military escalation could backfire and airpower alone is unlikely to achieve US President Donald Trump’s stated objectives, according to three sources familiar with the matter.
“Caine is looking for an off‑ramp,” one source said.
The general has raised concerns about the available military options in discussions with key Cabinet officials, including CIA Director John Ratcliffe, Secretary of State Marco Rubio and Vice President JD Vance, two sources confirmed, CNN reports.
He has also held side‑bar meetings with like‑minded advisers to coordinate positions before briefings with the president, stressing the limitations of air campaigns and the risks of escalation without ground forces.
One source told CNN that Caine’s approach is “his way of protecting the military.”
Trump has repeatedly signaled opposition to deploying ground troops in Iran, insisting that airstrikes could force Tehran to accept a deal on his terms. Caine and other officials privately view that outcome as unlikely and have sought alternative strategies that fit within Trump’s parameters.
Nearly six months into the Iran war which began with claims that Iran’s military capabilities had been decimated and remains defined by Trump’s pledge to prevent Tehran from acquiring a nuclear weapon — Caine’s stance underscores the absence of an easy military solution.
Caine’s spokesperson Joseph Holstead declined to discuss confidential conversations, saying: “We do not comment on anonymous, agenda‑driven characterizations of those conversations by sources who were not privy to them.”
A White House official praised Caine’s role, citing the “overwhelming success” of Operations Epic Fury, Midnight Hammer and Absolute Resolve. “The General always provides accurate, unbiased information and a host of options to the Commander‑in‑Chief,” the official said. The State Department and CIA declined comment.
Airpower limits
Caine has publicly acknowledged that “airpower has its limits.” That doctrine, reinforced by intelligence assessments, has made senior officials wary of aggressive new strikes.
In late July, Trump initially appeared ready to greenlight what he described as a “massive” operation but backed off after Middle East allies warned of Iranian retaliation against energy infrastructure.
Sources said CENTCOM elements and Israel favored escalation, but dwindling US stockpiles of key munitions also weighed against the plan.
Gulf officials have privately raised concerns about shortages of advanced American air defense systems, warning that their vulnerability could increase if Trump escalates.
Trump has repeatedly threatened to strike Iran’s energy infrastructure, but officials believe such attacks would not force Tehran to capitulate. Instead, they warn it would almost certainly trigger retaliatory strikes on Gulf energy facilities and further alienate the Iranian population rather than turn them against the regime.
