The progression of Islamic terror brings us to Jorge Luis Borges' writing. In his elegy “The Modesty of History,” the Argentine author wrote about the elusive nature of significant historic events. “I have long suspected that history, true history, is far more modest,” wrote the blind genius, “and that its essential dates may well be, for a long time, secret as well. A Chinese writer of prose has observed that the unicorn, for the very reason that it is so anomalous, will pass unnoticed. One’s eyes see what they are accustomed to see.” Borges went on to recall that the famous Roman historian Tacitus did not understand the Crucifixion, failing to grasp its significance at or around the actual time of the event.

The opening salvo of World War II was fired at Hitler’s failed 1923 beer hall putsch in Munich. At the time, the world reacted much like Tacitus did to the Crucifixion. It failed to notice it. World War III began with a boom on Sept. 11, 2001, when the world felt the first shot of global jihad. Nevertheless, over time, it preferred to ignore it or suppress thoughts of it. The Western world had forgotten the power of an unrestrained mass movement drunk on the successes of its brutality.

According to some estimates, Islamic State (IS) members now number as many as 20,000. The rate of people joining the movement is alarming. The percentage of people supporting it in the Muslim world and in Europe is horrifying. Its power, influence and draw are increasing with the speed of an untamed brushfire.

IS is jihad adapted to the age of the technological revolution. It is an amalgam of medieval ideas and 21st-century gadgetry. In effect, it is a closed circuit: IS makes clever, sophisticated use of technology as a magnet to attract young recruits, but it is also a product of the technological revolution. That is why it is so attractive, not only to Muslim youths, but to youths in general throughout the West.
