In authorizing military air strikes in Iraq—he is the fourth U.S. president in a row to do so—President Obama insisted that he was using military force for a limited, “humanitarian” reason and was not dragging the country into another war in Iraq. The strikes were designed, he said, to prevent the imminent genocide of an ancient religious sect known as the Yazidis, protect Christians who were fleeing from Islamic State fighters, and defend American personnel on the ground.
