It takes hours and hours at those temperatures for steel to begin to "weaken".

Spheroid iron can only occur at temperatures that liquefy iron, and then aerosilze it, and turn it into a spray... were any temperatures at WTC that hot, according to your government-based theory?

All of this was under pressure, and when floors started to collapse all everything was compressed and found the weakest exist point.

After the planes punched holes in these building, could what you say be true?

Iron in spherical form can't be found in regular dust absent some external source of heat - other than the temperatures of office fires.

Thermite is highly energetic and unsafe to use in enclosed spaces.

But the fact is that thermite wasn't used in the dismantling. Even if it was, there wouldn't be little iron spheres in the dust from the collapse days and weeks earlier...
:D
