If you haven’t, read the liveblog from the day, have a look at the one year on post, much of which still stands (though, thankfully, this country seems to be rather less hysterical about terrorism these days), and flick through the London Terror Attacks archive.

It’s important not to forget those that died. But although a memorial is being unveiled later today, the thing about terrorism remains that it exists to terrorise.

Four years on, the level of fear in London is back to what it was on 6th July 2005. People carry on their lives quite happily. The underground is packed with people not even giving a thought to the possibility of being blown up on the way to work. The majority of commuters this morning will not even remember that today is the anniversary of those deeply unpleasant events.

This is the best memorial.

Despite the best efforts of the terrorists – and the tabloid-whipped politicians scrabbling around in their wake with plans for detention without trial, stifling protest, DNA databases and countless other pointless draconian measures – our way of life has not been changed.

We, the people of London, were attacked – not the politicians, and not the innumerable armchair warmongers from around the world. The politicians and sabre-rattlers could do well to learn from our response – we dusted ourselves down, had a quick look around, and carried on with our lives.

The terrorists, hoping to have a major impact on the lives of everyone in this country, managed merely to kill and maim a few score innocents. They hoped to become heroes – they ended up little better than animals. And, four years on, they have been all but forgotten.

This is how it should be. If terrorists attack us to scare us and make us change our way of life, what better response is there than to carry on as if nothing has happened?
