Joint Chiefs of Staff Chairman Gen. Dan Caine is reportedly looking for an “off-ramp” to the Iran War and discussing his concerns about the options available for escalating the conflict in private conversations.

The details come from a CNN report, which also says Caine is not the only Trump administration official to privately be eyeing a way to exit the conflict. The report comes as the U.S. wades into its sixth month at war with Iran, as U.S. and Iranian officials have cycled through on-and-off negotiations for peace after the ceasefire, inked in April, crumbled in early July.
