Travel to Turkey, How to Insure travel in case of Travel Advisory and Escalation

I'm a US citizen, Planning a trip to Turkey (Flight into Istanbul, travel on both the european and middle eastern half), leaving October 15th. There is currently a State Department travel advisory on Turkey that is only cautionary. However, with the possibility of a military conflict in the region, I would like to be protected in case the travel advisory is elevated to "avoid all non-essential travel" and I want to cancel my trip or return early.

I've looked at a few travel insurance policies and none will cover the ticket cost in this case. (only covered in case of a "terrorist event" within a mile of the city of destination)

I'm not familiar with what typically happens to US originating flights that fall under a no travel advisory, Does the Airline typically reimburse/cancel the flight? Are there specialty travel insurance plans that will cover this eventuality? If tensions escalate while I'm in the country, what options do I have to protect myself financially for rescheduled flights and canceled bookings? In a real SHTF situation does the state department coordinate evacuation of US citizens?
