National security expert slaps down Rubio's 'implausible rationale' on Iran bombing

A historian and national security specialist was skeptical Monday of Secretary of State Marco Rubio's first public comments defending the Trump administration's decision to launch strikes against Iran.

CNN national security analyst Peter Bergen expressed doubt about Rubio's argument of an "imminent threat" and what could happen next in the war with Iran, which has left six American service members dead.

"Casey, I'm extremely skeptical," Bergen told CNN anchor Kasie Hunt.

"I mean, the Israelis and the United States are very closely allied. And their operations, as we've seen just now, are very closely integrated," Bergen added. "And Netanyahu has been in D.C., repeatedly. We've been moving massive amounts of military assets into the region since January, so I just find that kind of an implausible rationale."
