McGrath, I hope that any response will be a reasoned one, and I believe it will be. Revenge against the actual perpretators is impossible because they are dead. Their organization, when identified, must be targeted and rendered impotent. But more important, areas of severe tension must be stabilized. There is so much frustration in the World that extremism and more attacks are inevitable unless something is done to alleviate it. Without the frustration, people like bin Ladin (sp.) would not be able to build terrorist groups. At present all we can do is wait to hear if friends and relatives are OK, and try to help those who have suffered loss.
