The core was holding at least half of the building's loads, and the perimeter columns were weakest where the planes had impacted them. If you severed the core structure at the base, then all of the loads would be redistributed onto the perimeter columns, they wouldn't be able to take it, and the collapse would begin right where the plane impacted.
So we can establish that squibs shooting out the side of the building are in fact not squibs? I will argue further from there, if you concede this point.
