The horrific bombing and shooting spree in Norway in which more than 70 people were killed has led to an outpouring of shock and grief—and an irresistible chance for prominent voices in the debate over terrorism to reignite an old controversy.
Some bloggers and commentators who regularly warn about the threat posed by radical Islam were quick—in retrospect, too quick—to blame the mass killing on Islamic terrorism and to seize on it as a stark reminder of the dangers of insufficient vigilance, particularly by the Obama administration.
And when the main suspect turned out to be Anders Breivik, a 32-year-old right-wing extremist who was obsessed with immigration of Muslims to Europe, many commentators on the left who have warned about the dangers from extreme nationalists and racists felt vindicated for warning against an under-appreciated threat.
