In January, the world’s single largest terror attack since 9/11 was carried out by Boko Haram, an Islamist terrorist group in northern Nigeria. That incident, which drew only passing notice from the West, saw the slaughter of 2,000 civilians in the border town of Baga. Boko Haram’s oath of allegiance to the Islamic State last weekend raises questions about how this will affect the group. Given Boko Haram’s demonstrable ruthlessness in Baga, a better question would be, why aren’t we aiming to “degrade and destroy” it, too?
