A fair question. The catch would be with the word "pulverisation" itself, so we'd need to know your view of the degree of pulverisation experienced by the concrete, as I asked before.
My view is that much of the concrete was reduced to fine powder, some fine enough to be inhaled, sand and gravel (I'm not sure, though, how gravel can be produced without aggregate but the claims seem authentic)
So you "tend to lean" towards a CD hypothesis then.
I wrote : "... I tend to lean towards the hypotheses that other means besides aeroplanes and fire were employed to bring them down." This includes poor design/construction.
Why might it have been organised? How?
It is impossible to answer these these questions fully on a forum like this, certainly not on this thread! Here is a very condensed and incomplete list of some possible reasons:
Why might [CD] have been organised?
-To maximise the propaganda impact of the event.
Possible aims of propaganda event/total destruction of towers -->
-Enable war and massive increase in profits for associated industries, including Intelligence and domestic security industries.
-The US is a war economy and needs permanent war to survive. It needed an enemy to be feared as much as Communism used to be so it created one.
-A military response to global Peak Oil/energy crisis.
-Protect the Pentagon's fuel supply.
-To cover up/physically destroy evidence of/neutralise investigations into other crimes committed by the 911 perpetrators in the past, particularly massive covert financial fraud.
-Enable similar frauds in the present and future.
-Enable totalitarian structures and laws to be put in place in the US.
-Enable Imperial expansion and maintenance by motivating the US population to want war. All empires are resource-hungry.
-Enable global control of narcotics industry.
-Benefit other countries and possible participants in various ways.
-Many others
-Make use of decades of experience around the world in conducting covert military/Intelligence operations which often involve blowing things up!
Perhaps you can be the first to propose a narrative that could possibly explain some mechanism for the WTC destruction that doesn't involve impact damage and fire - alone - as the cause? Or will you continue to inhabit the nice, warm comfort zone you seem to have created for yourself where "nothing can be proved either way without the physical evidence" ?
I do not have such a narrative. I am not a military/demolition expert.
"Nothing can be proved either way without the physical evidence" is simply a statement of fact, in my opinion. The whole CD debate is sometimes considered a red herring because of this, though a fascinating one, and a distraction.
