Foreign terrorist organizations and those they inspire on American soil continue to pose the most serious threat of high lethality and high economic-social effect attacks against the nation. This threat is more serious than that posed by domestic white supremacist organizations.

I note this in light of the many pundits who claim that the opposite is true. They say that Salafi-Jihadism, the encompassing ideology of al Qaeda and the Islamic State, is today a lesser threat vector than violent white supremacy movements. Take New York Times columnist Paul Krugman. Marking the 19th anniversary of the 9/11 attacks on Friday, Krugman argued that “it’s now clear that the real threat to America comes not from foreign terrorists but from home-grown white supremacists. But you know what? That was true even in 2001.”
