The Yazidi may "not have iPhones", but they get the publicity that Christians do not. There are well over 100,000 Christians fleeing ISIS in the area. Bakhdida, also known as Baghdeda, Qaraqosh, Karakosh or Al-Hamdaniya is a Christian capital of 50,000 that fell to ISIS yesterday. Obama never mentioned these Christians. Instead he focused his sole action on protecting a few thousand Yazidi on a mountain top.
We must conclude that Obama wants to see Christians killed.
