I don't think killing people is good no matter how it happens, but I can see one thing that's almost good about terrorism.

-Governments needed a wakeup call; war isn't about two opposing factions standing in straight lines and shooting at each other. The American army was untrained in guerilla tactics when it went into Iraq, and they paid the price. When you're fighting for your life, you should be using any methods available to survive, and that is the future of warfare.

One other thing that really bugs me: Americans have gone ballistic over terrorism since 9/11, but terrorism has existed for hundreds of years in one form or another. We were just too ignorant to care about it till it hit us right in the face, and I don't think it will be possible to fully eradicate terrorism.
