living in terror of our own terror

Joan Smith in The Independent asks when we're going to get over it.

If anyone had told me, in the autumn of 2001, that we were less than 18 months away from what might become the world's first nuclear war, I would have thought they were insane. In the half century since Hiroshima and Nagasaki, no one has been that reckless or indeed that stupid – even, or so I thought, the Bush White House. Then came the twin towers and everything changed overnight, to the point where we find ourselves apparently on the threshold of a terrifying conflict in the Middle East. So the question I am going to ask, at the risk of causing great offence, is this: when is the US going to get over the events of 11 September?
She also soberly observes,
If the world has become a more dangerous place since 11 September 2001, it is not solely because of the activities of a bunch of Islamic terrorists.
