Before September 11, 2001, only some 400 people had pledged allegiance to Al-Qaeda. But now there are tens of thousands of jihadist militants on several continents. Terrorist attacks have multiplied around the world, straining relations between the West, its minority populations and Muslim nations. By violating the democratic values it claimed to be defending, the “War on Terror” launched by George W. Bush’s administration in the wake of 9/11 had the effect of a hammer smashing a vial of mercury. It scattered what had been a limited threat, turning it into a permanent global conflict – one that has provided fertile ground for recruiting jihadists and swelling the ranks of increasingly powerful xenophobic groups in the United States and Europe.
