The US needs to find an "off-ramp" from the war with Iran, Chairman of the Joint Chiefs Gen. Dan Caine reportedly told other top Trump advisers in private. Over the past few weeks, Trump’s most senior general raised concerns that military options on the table to escalate the conflict in Iran could backfire, and airpower alone is unlikely to achieve US President Donald Trump’s stated objectives, sources told CNN. “Caine is looking for an off ramp,” one of the sources was quoted as saying. Sources added that Caine is not alone in his view that the war has reached a crossroads. He reportedly discussed concerns about military options to escalate the conflict and raised the prospect of finding an off-ramp from the war with other key Cabinet officials, including CIA Director John Ratcliffe, Secretary of State Marco Rubio, and Vice President JD Vance. “I think it is just his way of protecting the military,” one of the sources told CNN, referring to Caine’s discussions with other top national security officials within Trump’s cabinet about the Iran war. Trump has consistently appeared averse to the idea of deploying ground troops in Iran, instead signaling he believes that air bombing can force them to agree to a deal on his terms. According to sources, Caine and others in Trump’s cabinet privately view that outcome as unlikely and instead have sought to develop other options that fit within the president’s own parameters.

When asked for a comment on this claim, Caine’s spokesperson Joseph Holstead told CNN: “We do not discuss the Chairman’s confidential conversations with the President, the Secretary, or other senior leaders, nor do we comment on anonymous, agenda-driven characterisations of those conversations by sources who were not privy to them.” The CNN report noted that while Caine has raised concerns, he has also been mindful of preserving his relationship with Trump, and been careful in how he conveys the potential downsides of military options when presenting them directly to the president, the sources said. Caine was “doing his job” by recently raising potential downsides of military options for escalating the conflict — including concerns about the already depleted US munitions stockpile — during a White House meeting with Trump and other top officials late last month, two sources familiar with the discussion were quoted as saying. But during the same discussion, Caine also made clear to the president that if he wanted to go forward with those operations, “we could absolutely wreck them,” one of the sources familiar with that recent White House meeting told CNN about the chairman’s message. Why US military options may backfire? 1. 'Airpower has its limits' "There is no easy military solution to end a war in Iran": This is what Caine has been arguing privately, according to CNN sources. They also emphasised the "limitations and pitfalls" of the available military options, including those that do not involve putting US boots on the ground.
