The humanitarian catastrophe that has brought more than a million refugees to Europe over the past year is not just a European crisis. The American public has remained detached from this tragedy, assured that it is some other nation’s problem but ignorant of the tangled origins of the calamity. The case of the Afghans, one of the world’s largest refugee communities and the second-largest group – behind Syrians – to arrive in Europe recently, should serve as a reminder that the origins of today’s predicament are neither recent nor confined to the refugees’ home countries.
