Actually, Iraq has an ancient and substantial Christian population...something like 10-15%. The pre-Arabic people, known as Chaldeans, have been Christians (mostly Catholic) for a long time.
The situation is somewhat better than North Africa... past Egypt (where a few Christians survived) Christianity was totally exterminated, all the way to the Atlantic. Everyone forgets, nowadays, that North Africa had a thriving Christian culture for centuries, and that the great Saint Augustine himself was a Libyan.
And their evangelistic efforts are non-existent under threat of death. That's not really freedom of religion now is it?
