While it may be hyperbolic to suggest that the July 2005 attacks in London changed the world, they certainly represent a watershed moment for Britain and Europe’s perception of the threat from global jihadism. When Mohammed Siddique Khan and his fellow plotters detonated their suicide vests on the London transport system, we were all in shock. This is not only because we had just witnessed one of the worst terrorist attacks in British history, but because it was carried out by one of our own; seemingly well-integrated British-born men of Pakistani origin.
