There are five times as many Muslims in the United States as there are in Belgium, but the United States is not a hotbed of homegrown Islamic extremism. We've suffered some acts of terrorism since 9/11—the mass shooting in San Bernardino, the Boston Marathon bombing and the massacre at Fort Hood. If American Muslims and European Muslims were equally predisposed to jihadism, we'd experience roughly five times as many attacks. But we don't, mostly because Muslims feel more at home in the United States than they do in Europe.
