Citing three sources familiar with the discussions, CNN reported that Caine raised his concerns with senior officials including, CIA Director John Ratcliffe, Secretary of State Marco Rubio and Vice President JD Vance. The report said Caine and other officials believe airpower alone is unlikely to force Tehran to accept US demands, despite President Donald Trump’s continued preference for avoiding a ground invasion. Trump ultimately postponed the operation after Gulf partners warned of possible attacks, said the report. Noting that Caine has warned Trump about the military risks, CNN said he also emphasized US forces could inflict significant damage on Iran if ordered to escalate.
