I wouldn't be surprised if we take in 2-3 million Iraqis over the next few years. 10%-15% of the country probably.

Most of them will be Arab Christians, now the targets of the jihadis with the sectarian conflict and the new constitution that declares Islam their official religion. This was inevitable as many many folks pointed out.

Number of Christians in Iraq prior to the invasion was put at about 3% of a population of 25 million.

If you take in 2 - 3 million Iraqis, it’s mathmatically impossible for ‘most of them’ to be Arab Christians.
