Reality check in Paris
The late Christopher Hitchens warned us years ago about the reality we are facing:
What nobody in authority thinks us grown-up enough to be told is this: We had better get used to being the civilians who are under a relentless and planned assault from the pledged supporters of a wicked theocratic ideology. These people will kill themselves to attack hotels, weddings, buses, subways, cinemas, and trains. They consider Jews, Christians, Hindus, women, homosexuals, and dissident Muslims (to give only the main instances) to be divinely mandated slaughter victims. Our civil aviation is only the most psychologically frightening symbol of a plethora of potential targets. The future murderers will generally not be from refugee camps or slums (though they are being indoctrinated every day in our prisons); they will frequently be from educated backgrounds, and they will often not be from overseas at all. They are already in our suburbs and even in our military. We can expect to take casualties. The battle will go on for the rest of our lives. Those who plan our destruction know what they want, and they are prepared to kill and die for it (emphasis added).
