I highly, highly doubt any Egyptian living in Iraq for a period of time would not be able to pick up the dialect rather quickly.

Except when you're working for an occupying military force, you're not really "living" in the country you're occupying. Unless you're native, you're living on a military base -- i.e. with the occupiers, and not with the locals.

Which is one of many, many reasons why these kinds of military operations tend not to work so well.
