The intractable, insidious conflict between Islamism and the West

When al Qaeda struck at the United States in 2001, its targets were hard symbols of American power and decision-making: the Pentagon, the Capitol, and the financial capital. When ISIS struck Paris on Friday, its targets were soft symbols of Western lifestyle: sport, restaurants, a secular concert. People eating, drinking, and laughing at night for their own pleasure.

ISIS knows our thinking. It knows how to make us afraid.
