I presume Iraq is ICAO, and they have the right to decide whether to accept other licence types or not. Willie is right, however there were many pilots in India working on FAA licences which was awkward due to the lack of check airmen; pilots had to go home to get check rides on their own licences to keep their FATAs up to date - it's a bit better now with local medics who are FAA approved, for example.
Whereas most ICAO countries will accept JAR or ICAO for validations, it sounds to me like you're asking other people to comment on Iraqi politics, rather than asking a legal question.
