The only thing 9/11 has done for me is annoy me. (I'm sorry if this is offensive to you, but on a pro-american forum, I'm bound to be suspended for this post)
The American government took down a couple of skyscrapers as a plot to invade the middle east and secure oil supplies because as a country it's totally renewable-energy-retarded. Watch, they will invade the UK next to get at our bazillion gallons of oil we have under the Falklands.
So I was a kid when 9/11 went down (no pun intended), I stayed up all night watching it on the news, totally fascinated. That was the first time I've ever seen a world leader declare war in my life. Anywho, it's done nothing but bug me since then to be frank. Every year, boo hoo, even British news channels are clogged full of the 9/11 hype. I bet the majority of Americans could not name the date London was bombed by islamic extremists. To be frank again, it's time to put it behind you and move on.
Perhaps you could mourn the date of the oil spill and contemplate your countries vile greed for black goo when the sun is capable of fueling your nation, but you just won't because too many people get rich from Oil.
(I seem to have spent that entire post ranting about Oil! ^_^ Not my intention, but hey. Please don't be offended. I seem to be on probation for dissing Israel, I'd not survive being accused of dissing American too)
