Iran has threatened to strike the US west coast with offensive drones in retaliation for American military operations, according to an FBI warning issued to California police departments.

This is an ABC News report and it reads to me like the kind of standard thing that police dept’s would send out at a time like this, not some kind of imminent operation.

There is some risk-off trading on this and that kind of attack is the kind of thing that could draw the US into a long, messy ground war.
