SHF, Here is what I think. You are assuming that bin Laden sat down and planned out the whole thing, and I don't think he works that way. Al-Qaida does not carry out attacks itself, but provides resources for other groups to carry them out. In some cases the ties are tight and in other cases very loose. These groups, or cells as they are being called, have to curry favor from Al-Qaida. A new group that has plots and plans may get a litlle help from Al-Qaida, but when they carry something out, then they are in a position to ask for more. The more they do the more they get.
It's hard to guess just what bin Laden knew, ahead of time. He may have know a cell was going to carry out an attack on U.S. soil and he may not have known. I really doubt he knew all the particulars. Thus, he was able to say " I didn't have anything to do with it" When we finallly see the proof that bin Laden is tied to 9/11, it will be by the money trail.
Also, I think it's a mistake to put bin Laden and Al-Qaida in the same basket with the Taliban. Up til now bin Laden has always been an asset and not a liability to the Taliban. They are hard liners, but they didn't have many friends before this and they are getting fewer. They talk tough, but it's hard to know what they are talking about behind closed doors.
I do agree that bin Laden and Al-Qaida, and others would like to get the whole region to rise up against us. They try very hard to tie us together with Israel.Of course mentioning the Palestinians. They always bring Muslim religion into it. And in recent years, in most terrorist attacks no one group takes credit. This makes it a Arab vs America/Israel conflict
