MOSUL’S CHRISTIANS Say Goodbye.

Since the Americans invaded Iraq in 2003, he estimates, Mosul’s Christian population dwindled from 35,000 to some 3,000. “Now there is no one left,” he said. Most of them have joined the estimated 500,000 refugees who have fled the ISIS advance; many of the Christians, including the archbishop, have opted for the relative security of Iraqi Kurdistan. . . .

In 2003, it was estimated that some 1.5 million Iraqis were Christians, about 5 percent of the population. Since then, the overwhelming majority has reacted to widening sectarian conflict and a series of terrorist attacks by leaving the country.
