I think Bush is trying to preserve the buildings etc. After all he does want the money this war is costing the USA quite alot of money seeing as the canadians are starting to catch up with the USA doller bill.
P.S There are also many facts on how it is nearly impossible for a steal framed building to melt or even COLLIED into it self under the heat given by the airplane explosion. And even if it was hot enough, people have done studys and the chances of two steal framed building colliding into themselfs in the same location are 1 then over a couble billion.
Uhh..I really have no right to talk here seeing as I am from canada, I'm just saying the things i've heard, they mey be wrong.
