Terrorist Attacks on the U.S.
This is probably the most visual terrorist attack ever. It was like a movie, even the weather was perfect. It will change the world, and the feelings about terrorism everywhere. This might be the end of reason and tolerance when dealing with terror. The insanity of the plane-crash into the World Trade Center is how these terrorists are using up all emotional ammunition of all terror organisations in one operation. Nobody wins a war fought like this.

Some thoughts off the top of my head: people in hostage situations will expect to die and not attempt to survive, planes which are hijacked will be shot down rather than permitted to deviate from the course, if the operations were not originally suicide missions, that's what they will end up as...

Perhaps this denotes the end of terrorism as an effective means of blackmail; the rhetoric of terror only works as long as there is hope that lives can be saved, that listening and negotiating will lead to less damage than a quick strike. After the morning September 11th New York time, all any government will think of at the slightest threat of a terrorist act is to keep the damage as small as possible - if they have to sacrifice 100 hostages to save thousands of lives, so be it.
