The rule of terrorism is to first attack then follow with lots of threats of attacks. After an unexpected real attack comes threats of attacks followed by a real attack and then repeat.
They have every reason to not announce the real attacks and contantly announce fake attacks.
Either way, they will pay.
This is my line of thinking also. Why and how would this group of Al Qaida maggot cells have become stronger over the past year? If anything they are running around like the keystone cops running into each other trying to organize, money depleted,using empty threats to make us rethink striking Iraq, probably their major 'base' in all this.
Logically, why didn't they hit us with everything on 9/11/01 before we had the chance to respond? Doesn't make sense. Sounds like sabre rattling to me, from the ghost warrior Elvis bin Laden ordered up by his loyal, somewhat dispersed, followers.
