Which building are you thinking of? If you are talking about the towers themselves, doesn't this look like "significant, recognizable resistance"?
I don't think showing a picture of one of the main towers TURNING TO DUST at near-free-fall speed, reminiscent of a pyroclastic cloud, is going to help your case here. That, together with the 1400 toasted vehicles up to a half mile away from Ground Zero, are evidence of the use of nukes. Nothing of that size has ever been demolished by explosives so we're looking at uncharted territory here.
If you are talking about WTC7, then why would every beam have to be weakened at the same time? Did you watch the videos? The models show the internals of the building coming down first, leaving the outside waving and swaying, but intact (as in the footage), then the outside coming down. It wouldn't require the entire structure to weaken at the same time.
What you described is exactly how controlled demolition is designed, so that the building collapses in on itself on all four sides as it falls straight downward. Just in case you don't know, the official government explanation is that some very well placed diesel tanks ignited and simulated a controlled demolition.
You can believe whatever you want, but trying to convince me that the official story is true after all the research I've done is tantamount to going back to the Watchtower and believing it after reading every thread on this site.
