threeangels, SofiaAmes is American too and both of you are bound to be more affected by the whole thing - when it's your own country and your own people being attacked it feels much worse.
It's not that people here don't sympathise with the victims but, for instance, if your country hadn't felt confident and impregnable then it would have had better airport security and maybe none of those guys would have got on the planes.
We do tend to perceive George Bush as a loose cannon - saying things like "either you are for us or for the terrorists", which is far too simple when you're talking about world politics - and, as SoupDragon says, he is still up there interfering - and having Tony Blair cosying up to him makes the UK more of a target.
There is also the question, this week, of the Kyoto agreement about reducing the use of fossil fuels, and America refusing to ratify it because Americans expect to be able to buy cheap fuel, drive big cars, run massive air-conditioning units all summer etc., whatever effect it has on the rest of the world. (Our regular gasoline costs $5 for a UK gallon - $4 for a US gallon. Most of that is tax. How much is yours? Would you use less if it cost $4? Would people vote for Bush if he did put that much tax on it?)
Most of us don't hate America or Americans but America does behave, in world terms, as if nobody else really matters much...
