If the Iranians get their hands on any surviving aircrew, they might consider hosting him as a valuable honored guest in high command headquarters as protection against decapitation strikes. However SF might want to have a say.
I suspect that assuming the crew do not fall victim to irate civilians on first contact, the authorities will actually treat them relatively well. Primarily to maintain the projected moral high ground and to avoid alienating the. countries that have said no to supporting Trump. Given that this is not ISIS held territory or the old Vietnam scenarios, this rescue mission seems incredibly high risk for the actual risk being negated. Stooging around in daylight at low speed, in an area where a fast jet was shot down, with twenty or so blokes in platforms with no escape systems?
