Connecticut Democratic Sen. Chris Murphy said President Donald Trump is reportedly planning to resume the Iran war after the midterm elections, a proposal Murphy called “insane.”

Speaking at the Middle East Institute, Murphy said officials had discussed in detail what renewed military operations would involve and challenged reports that the plan would be brief.

Murphy said he and others had been briefed on the plan but could not disclose its details; he argued renewed operations would fail to meet their objectives and set off another cycle of escalation.

Meanwhile, the Pentagon is reportedly reinforcing missile defenses, repositioning troops and preparing additional warships and aircraft for possible strikes on Iran’s nuclear facilities and military infrastructure.

Murphy warned that renewed operations could lead to devastating escalation and undermine the United States’ commitment to the rule of law, even as Trump had recently signaled the war might end soon.
