I think it's safe to say that the Israeli Mossad knew a lot more than we know about events surrounding 9-11. Peter Dale Scott talks about conversations he has had with CIA and State Dept officials concerning the contracting out of intelligence to foreign agencies. PDS says they neither confirm nor deny that this was the case before or after 9-11.
The Mossad actually did warn the CIA repeatedly about probable al Qa'eda attacks inside the U.S. in the months and weeks leading to 9-11. CIA officials themselves said that they, in turn, warned the Bush WhitHouse. Repeatedly. The Israelis apparently appealed to the Russians in order that [i]Russian[/i] intel alerts would seem more credible to Bush hawks. And then warnings were dropped in their laps from world-wide intel agencies, which were also ignored by Cheney, Bush, the FBI, and so on.
Naomi Klein says she does not support conspiracy theories surrounding 9-11 and prefers to decribe it as a deliberate adherance to laissez-faire attitude by the Bush admin. That's a safe bet. But it was Hungarian-Canadian socialist Karl Polanyi who said that laissez-faire came about by selective state policies which required planning and enforcing. Therefore, laissez-faire was planned but planning was not.
