The building that still stand are not made of wood like the rest that were burned down BY CARPET BOMBING not by an atomic bomb. You would not see any buildings standing if that type of weapon was used. You would also see debris strewn about on the streets. You would also see a pattern of debris laying outwards from the point of impact, but that's not what we find in the so called ground zero.
Again and again the government lies to its people and the media uses the lies to create more drama so they can profit and keep you in a constant state of fear.
