I certainly cannot expect you to agree with all of my opinions. But to continue the discussion, the purpose of terrorism as a tactic is two fold, the first is to instill a fear among the general poppulation. The second is to use violence in unimaginable ways against otherwise innocent people to cause a change in policy by various governments.
In which case our reaction to 9-11 has played directly into the terrorists hands. Suspending habeaus corpus and the 5th amendment, forcing normal Americans to go through idiotic rituals to board an airplane, and baiting America into two very long, expensive, and deadly wars that has divided the poppulace, strained the military and alienated some of our closest allies.
Never in thier wildest dreams did the bastards who crashed those planes into the WTC imagine they would be so successful. They managed to bring down the buildings, but we have allowed ourselves to let them win by the shift in our domestic policy towards our own citizens.
