Wise words Capt WB, my sentiments exactly.
Whilst it would be deeply satisfying to make someone pay for this atrocity, civilisation takes a step back when the "Eye for an eye" priciple is applied. I don't like the term, but Western governments needs to take a more holistic look at the problem of World terrorism, think about their foreign/economic policies and consider if they're likely to encourage more bin Ladens to take up arms.
In the near future I hope the US/NATO can establish who was responsible for the events in NY and Washington and teach them a very hard lesson. In the medium to longer term the World needs to do some soul searching and decide if we want to live together or bomb the sh*t out of each other until The Big One.
