If you're going to accept the job, and you're going to be based out of Baghdad, make sure you stay on the airport (although the food at the Airport Hotel is atrocious, the takeaway from the Happy Store is far better). Outside is still too risky.
Flying is easy - ATC is still provided at low levels mainly by ex-pats. Comms are pretty poor at times but there's so little traffic low down you're unlikely to hit anyone else. You'll find it interesting, but you'll be glad to leave - the country has a long way to go! There's no other risk. Carry lots of US Dollars to "smooth the way" (if you get my meaning).
If you can be based out of Erbil in the north - different story. Shopping Malls, Coffee shops, Restaurants. You can walk the streets in safety.
Anything else you want to know, feel free to ask.
