Over the last few weeks, Chairman of the Joint Chiefs Gen. Dan Caine has privately made clear to other top Trump advisers that the US needs to find an off-ramp from the war with Iran — because the military options on the table to escalate the conflict could backfire and airpower alone is unlikely to achieve Donald Trump’s stated objectives, according to three sources familiar with the matter.

“Caine is looking for an off ramp,” one of the sources said bluntly.

Caine is not alone in his view that the war has reached a crossroads. He has discussed concerns about the military options for escalating 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, two of the sources said.
