Jessie,
Given that all I can provide is words on a screen, I doubt that there's much point attempting to persuade you of the hijack theory. Moreover, I don't have any access to the kind of evidence that I would convince me, or anyone else, of it. Hopefully some will be forthcoming...
Even so, I don't believe that what happened on 9/11 was in any was instigated by the US government. I don't think there's any real need, and I don't feel that Northwoods is really a viable precedent, given that a)it didn't happen and b) I've seen no real proof that the plan was even drawn up.
I do think that there was a 'conspiracy' to draw the USSR into a costly and protracted war in Afghanistan, and that Osama Bin Laden was a CIA asset during that war.
I do believe - because of an intelligence report made public by the Dutch commission into the failure of DutchBat to prevent the massacre at Sbrenica - that the CIA used its contacts with the mujaheddin to shift men and weapons into Bosnia to fight against the Serbs. We all know that they went there, somehow, after all; it isn't inconceivable that they didn't have assistance from the CIA. I imagine it could well have been a useful quid pro quo for both sides. But, I have only the one source (and access to it is fairly restricted), so I can't corroborate it.
Still, OBL may have proved quite useful to the Americans, and if he was an asset, I presume he would have had maintained his contacts with the CIA. There's a report in Le Monde that alleges that he made contact at some point in the run-up to the attacks.
Now, some people will argue that this is evidence that the CIA got him to do the job. I disagree, because of the reasons I have been reiterating here and elsewhere: you don't need to kill your own people to go to war. There are easier ways.
Likewise, there are simpler explanations. I don't buy for a second this crap about remote controlled planes. But I do think that OBL may have persuaded his contacts that he was carrying out a job for the US, and so assisted the hijackers' entry into the country and their getting flight training courses.
That, to me, is a hell of a lot more believable than remote controlled planes, and it explains the reluctance of the USG to release any evidence - after all, it would be rather embarrassing to have to admit that your own pet terrorist has bitten you quite badly, wouldn't it?
That is as conspiratorial as I get on this though.
As for whether anyone will believe my argument - well, I don't have anything with which to back it up, just a few articles here and there which point towards a vague possibility.
My argument, though, manages to fit quite closely to all the information about the attacks that has come out into the public domain, without having to invent any new technologies. Occam's razor, I guess. And that's if it's even the case - it could well be that everything happened exactly as we are told it happened.
But to be quite honest, I'm not sure I care any more. Those people are dead, and they aren't coming back. We are unlikely to ever know exactly what happened - but that's the way life works. We never know very much for certain. We just have to make do with what seems to make the most sense, without going off into a haze of delusional paranoia.
