No, not because they blow people up. The number of people they blow up is sufficiently trivial that only paranoid loons would even bother worrying about it.
In any case, it’s hard to see how removing 3000 New York bankers from the equation could have failed to make the world a better place. Fuck off with your whiny, obscenely wealthy shrink-going self-obsession, and endure some of the misery and suffering you normally only inflict on other people for profit. Win-fucking-win (see also John Monckton).
Returning to the Islamists, though, I hate they way they provide a cover for would-be tyrants and process-crazed bureaucrats to demand or impose whatever the hell stupid measures they like. Ian Blair and some Russian apparatchik were both interviewed on today’s Today programme; both of them blethered on incessantly about the terrible measures required to deal with the terrorist menace (the fact that prior knowledge of British or Russian politics is the only way to tell between the two country’s terrible measures – detaining people for three months without evidence versus demanding a government license for all NGOs – is also worrying, but not the point).
The point is that because The People are scared that these freaky types in funny hats and odd-coloured skin will achieve the singularly unlikely feat of a not-utterly-pathetic-and-laughable terrorist attack – say, one which kills or mains more people than a year’s worth of road casualties – governments in both countries can get away with proposing these measures without being immediately overthrown and hung from makeshift gallows for tyranny. Stop it, you pathetic wusses.
