David McWilliams: West finally needs to admit all radical roads lead back to Saudi Arabia
Yesterday, few places felt more vulnerable than the Central Line, as I sat with my son, deep under London's streets. The train stopped suddenly around Queensway and we both looked at each other, indeed everyone looked at each other. No one needed to say anything; everyone understood what everyone else was thinking. This is what terrorism does, it terrorises; and, if not quite terrorise, it puts doubts in your head where there weren't any before. That's enough.
London is full of mosques, the vast majority of them frequented by people who have no truck with those who murdered so callously in Brussels, but some people who go to some mosques obviously do. This is the only conclusion that you can draw.
Young men and young women become radicalised because someone else teaches them. It doesn't happen on its own. People who once were happy to be barmen don't turn into soldiers of Allah overnight. It is a process.
