We Americans are accustomed to regarding political rhetoric much as Dr. Johnson did epitaphs. "They are not," he wrote, "given under oath."
In other words, we don't expect public men or women to speak the truth from public platforms. When it comes to our own parochial affairs, there's probably a bit of weary realism in that. However, this casual expectation of rhetorical hypocrisy has inhibited from the start our ability to recognize and deal with the threat posed by Islamist radicalism.
Time and again, the spokesmen for these movements have told the world precisely what they intend. Time and again, the scant handful of Americans who bothered to take notice have dismissed what was said as the product of political alienation, as the consequence of economic marginalization, as a hangover of post-colonial insecurity or as tactical bluster.
No. These people mean exactly what they say, and they mean it for precisely the reasons they say they do.
