^^ Not a very convincing argument there Duck.
So a very few "low rise", steel framed buildings have partially collapsed due to intense fire. A telling quote from one of your links below.

"Contrary to popular belief September 11, 2001 was not the first time a steel framed building collapsed due to fire. Though the examples below are not high rise buildings, they make the point that fire alone can collapse a steel structure."

The fact remains that no other high rise building has ever collapsed in such a manner so closely resembling a controled demolition, due to fire. Let alone 3 of them on the one day.

Maybe do some more research and see what you can come up with.
