Terrorism
'[Islamic terrorism] is a far graver threat in terms of civilians than either the Cold War or the Second World War,'said Sir Ian Blair, last week. I can't find the entire speech for the context, but on the face of it given around 50,000 civilians died over the Second World War's six years in London alone (43k in first Blitz, more than 7k in 'mini-Blitz', a weekly death toll twice as high as the July 2007 bombings) he's either talking nonsense, or he is referring to atomic weapons. I'm not even sure the mass attacks on aircraft would get you there.
