Unlike the America thread which you are comparing this to for purposes of your warnings, Cloud, terrorism, by definition, is not a good concept, whereas America has both good and bad sides to it. A terrorist is a person who uses, as was posted in the definition early, violence, intimidation, and other tactics by which to achieve their ends. You might claim that the ends justify the means, in which case that is a "good" achievment of terrorism, but I tend to be of the opinion that the end does not justify the means in cases such as this.
