<< it takes more than just money, it takes logistical assets, the kind of stuff that governments can plan, that I don't know if one single man can mastermind, even if he's rich. >>
bin Laden and his advisors have been masterminding terrorist attacks for years, I think he's got the logistics covered.

There is now evidence that more than a dozen terrorists took flight training in the U.S. costing upwards of $10,000 each. It now looks like even more targets were planned, but those plans fell through for some reason.
Someone was funding this, rather well. I don't think it would take Iraq to do it, bin Laden is filthy rich, unless Iraq got with bin Laden and said "We want to help you get back at America in a really big way!" It's possible that Iraq just wanted to be a part of all this, though its rather sloppy to allow those outside your closely-knit group to get involved.
