FOUR YEARS LATER, THE QUESTION:

Four years later, terrorism remains a problem around the world, as we have seen in Bali, in Madrid, in Israel, in London, and, of course, in Iraq. Yet, it would seem, not in America. While America remains alert and, some would say, hypersensitive to the risk of another attack, none has come. Our buildings, our buses, our airplanes all are surely tempting targets to the likes of Al Qaeda and its sympathizers. Yet, four years later, they have not struck. In the tense days after 9-11, such a stretch of safety would have seemed like wishful thinking. And yet, that’s what happened.

Why?
