Good questions - these are simply my speculations...

1. Are you sure there were no cutter charges in the top 30 floors? The support columns (which are in the center of the building) could have been severed, you wouldn't neccessarily have to see the cutter charges. This was in an earlier thread, where we argued that 2 explosive systems must have been present - an internal system severing the main core columns, and an external - to create the giant dust cloud, so it wouldn't look like a clean demolition - like WTC 7. We're no experts here, but if you check out some other controlled demolitions, they are fairly clear of smoke clouds until they completely collpase. I think its a pretty fair statement to make, but has not been elborated on by professionals.

- and yea, any complex sequence of explosives was entirely possible, and with a mission this crucial, im sure they took every precaution to sell it as a collapse.

2. We can't know exactly but consider this - they invaded, didn't they? At the time, the whole country was behind it and Bush's approval rating was in the 90-100%. They were drunk with power, and didn't have to do much to convince us to go to war. So - they didn't do much - just a forged document and some blurry aerial photos worked just fine. Wars that drag on always lose support. They are still in office for a second term. Seems like they were pretty successful to me. They have more power than ever. Despite leaving a trail of breadcrumbs that this heavily cencored movement has picked up on, 9/11 and the subsequent wars were carried out with military precision and they are to this day, calling the shots.
