EVERY September 11th America mourns the people al-Qaeda murdered in the atrocities of 2001. And every year the anniversary compels an assessment of how the “war on terror” is faring. After a year that saw a successful terrorist attack and two near-misses on American soil, it is hard to be upbeat. In November Major Nidal Malik Hasan, an American, killed 13 comrades in Fort Hood, Texas. On Christmas Day Umar Farouk Abdulmutallab, a Nigerian, failed to set off his bomb properly on a Detroit-bound passenger jet. And in May Faisal Shahzad, a naturalised American, left a car bomb in Times Square in New York.
