Those goofy 9/11 truthers are trying to say that because a raging inferno in China didn't cause the building to collapse - when it was roughly the same size as World Trade Center building 7 - that shows that building 7 was demolished. The truthers point to other raging infernos, also, where no collapse occurred.
And they point to numerous structural engineers, architects, scientists and demolition experts who believe building 7 was intentionally demolished.
But these think-they-are-smart whackos forget a basic fact . . . China is a communist country.
In fact, China has never signed any treaties binding the country to the modern laws of physics. Sure, they have adopted many Western ideas of capitalism, and they looked really modern during the Olympics, but don't let that fool you. The Asians have only partially adopted Western ideas and theories.
While the physics principal of "thermal expansion" governs in the United States, and thermal expansion is part and parcel of the American ethos (official government press release), that particular "Western" principal has not been adopted by the communist Chinese regime.
9/11 truthers are simply naive about geopolitical realities in non-Western nations. The idiots.
