2000. we're learning from the same sources that sidiqi had connections with muhammed atta at that time. so his sort of radical tendencies, if you will, go back quite a long way. but now it appears he's given intelligence officials a lot of information allowing them to learn a lot about these plans and about the people behind those plans. nic robertson, cnn, abu dhabi, the united arab emirates. crunkshank is live in london. give us an idea of the structure of al qaeda today. when we hear top commanders have been killed, is there somebody in place to replace them? or does that matter less today where al qaeda operates in cells around the world. what's your sense of how big an accomplishment this is? >> the true headquarters of al qaeda is still in pakistan and it's from pakistan it's being hatched showing al qaeda is resilient and able to pressure the west.
