Look at the stuff about the mast, at the top of the page. And those were HUGE support columns. Govt-controlled wikipedia has changed its tune over the past few years and now talks about the walls being the load-bearing element, but that's not true.
As far as Brzezinski, he's the man now running America's foreign policy. He did under Carter and he's doing it under Obama. Brzenskinski's goal is to create what he calls a crescent of fire in the Middle East. A crescent of wars (Pakistan & Iran will complete the crescent). This crescent will deny China oil from the Mid east and block it's overland trade routes to Africa. China will be forced to turn on the former Soviet Union for natural resources. That's the Brzezinski plan.
The Neo-con wars and the Obama wars are all built on the 9/11 lie.
