No, it's not. The purpose of terrorism is to create terror. They've been fairly successful at that, although probably not as much as they hoped. The real questiion is, what do they expect our response to be. And of course what it really will be. They may be in for big surpise, at least I hope so.
What if they just want to kill us?
The evil one has the hunger of a serial killer.
