Most Iraqis deported by Saddam at the beginning of the war spoke excellent Farsi. I happened to have two really good friends that were deported by Saddam and there was no way you could tell that they weren't Iranians.
Unfortunately, some of these people, possibly due their hatred of Saddam and his Baat parti, tied their knots to IR and became more loyal to the regime than most. This animal is a prime example of that.
