The public outcry attending President Trump’s attempted travel ban from seven radical Muslim states, designed to prevent foreign terrorists from entering the country, has diverted attention from the longstanding danger of homegrown jihadists. As early as 2007, the New York Police Department (NYPD) released a 92-page report documenting the extent of al-Qaeda-linked homegrown jihad in Europe and the United States. The Obama administration, however, went out of its way to ignore, deny, and whitewash any homegrown terror that smacked of Islamist violence. But a decade later, al-Qaeda has been all but eclipsed by the Islamic State (ISIS), which has skillfully used social media to become the foremost purveyor of jihadist indoctrination in the West, creating a “virtual caliphate,” extremely dangerous and easily accessible to vulnerable men and women from a variety of backgrounds in a manner al-Qaeda was never able to achieve. Even were all territory now under ISIS control to be retaken, this virtual caliphate could continue to pose a major threat.
