the slight difference...
Tail' is correct in asserting that "terrorism has been with us for years" but the difference now is that, unlike previous waves, the terrorists actually seek from the outset of their planning, to kill themselves too while attempting to make their point. That's a particularly radical muslim thing to be aiming for which has altogether too much tacit support, from even the less radical in that community, for my taste. Outcry after such events seems often to be more like 'we condemn this attack.... but you have to understand their point!' I don't accept that when ordinary people going about their daily routine are the targets.
