On days like this, I am glad I live in a small city. Of course with Canada's Pacific Naval Base mere miles from my home, I realize we are still a target, just as in the 80s I was aware that Seattle would be a likely target for a Russian nuke.
Unlike New York, Madrid, and other cities which have been targeted by terrorists, I can identify with the landscape of London. I have been in the underground stations which were attacked; I have been on busses like the one that was torn apart. I walked the streets that were jammed by emergency vehicles. It hits much closer to home.
My first thought was, "Fucking IRA. Why don't they just give up." When I saw the claims by Al Queda, I just shuddered because it gives Bush and Blair more authority to screw with individuals' rights. If the attack was planned, it was almost certainly to coincide with G8; it's just a "bonus" that the 2012 Olympics were just won by the city and everyone was in a celebratory mood.
The anti-terrorist rhetoric is already in full-swing... I expect by noon our time I will not be able to watch TV without having a tantrum.
I often wonder how this era will be recorded in the history texts of the future; I think it can be compared to the cold war for the psychological effect on the average person but it differs in that many more lives have been directly affected by terrorism.
