Displaced Iraqi Christians unsure whether to return home

Iraq was home to some 1.5 million Christians before the rise of the so-called "Islamic State" (IS), which led to persecution of Iraqi Christians, who were forced to convert to Islam. The majority ended up fleeing the country. Now that Iraqi forces are trying to retake Mosul from IS, Iraqi Christians appear divided about whether they want to return home even if IS militants are flushed out.
