And of course, last October in Paris and other French cities, hundreds of buildings were torched and tens of thousands of cars burned by Muslim "youths" through weeks of rioting, while both the French government and most of the "responsible" experts denied there was any radical Muslim component to the greatest urban violence to hit France since World War. It was all to do with poverty and teenage angst and alienation.

Of course poverty and alienation can't explain the Iranian student in North Carolina. He has just received one of the finest educations available to a privileged American. He reportedly has received advanced degrees in philosophy and psychology from one of our top universities.

The media has pointed out that there is no evidence he was connected to Al Qaeda or another terrorist cell. But that is exactly the point. As I discussed in my book last year, the threat to the West is vastly more than bin Laden and Al Qaeda (although that would be bad enough.)

The greater danger is the ferment in Islam that is generating radical ideas in an unknown, but growing percentage of grass-roots Muslims around the world -- very much including in Europe and, to a currently lesser extent, in the United States.

A nation cannot design (and maintain public support for) a rational response to the danger if the nature and extent of the danger is not identified, widely reported and comprehended.

What are we dealing with? A few maladjusted "youth"? Or a larger and growing number of perfectly well-adjusted men and women -- who just happen to be adjusted to a different set of cultural, religious (or distorted religious) and political values. And does it matter that those values are inimical to western concepts of tolerance, democracy, equality and religious freedom?

The public has the right and vital need to have the events of our time fully and fairly described and reported. But a witch's brew of psychological denial and political correctness is suppressing the institutional voices of government, police, schools, universities and the media when it comes to radical Islam.

As the danger grows but is not publicly described, the public will first be ignorant and fail to demand sufficient remedial action.

But as incidents and rumors are encountered over time, the public mind will inevitably suspect the worst and demand the strongest action. Demagogues will emerge to gratify that vox populi. (The Dubai port deal is a small example of such a process -- although in that incident the threat is real and there are many sincere and rational voices amidst the many demagogues.)

Institutional voices are not being responsible by suppressing honest description of radical Islamic events. Denying the existence of evil (or refusing to be judgmental about it) has never proved a reliable method for defeating it. Hell is presumably filled with souls who didn't understand that point.
