and no one knew how debris could make building 7 also collapse so efficiently.

When building the world's tallest towers in one of the most densely populated areas on the planet...

Designing it to collapse straight down is a good idea.

from the “dancing israelis” scandal (Mossad agents posing as art students)

I mean, that was real...

But more likely they were just celebrating upcoming war, and didn't know ahead of time. Worst case scenario Israel may have knew it was coming, I doubt the people watching were told, that's too risk for them to know ahead of time, just tell them "you'll know it when you see it".

and previous attempts to take the towers down,

Would be crazier if they got it on the first try...

the ease of which nearly completely in tact passports were conveniently found,

They tend to make passports and other important IDs pretty sturdy...

presence of thermite on the ground, supposedly testimony that the twin towers were built to withstand the very thing that took them down, the suspicious insurance purchases by the Twin Towers owner and some other company at the port.

I don't know about all that...

But you can't design a skyscraper today to withstand a passenger jet slamming into it bro...

It's a giant plane, it's gonna fuck up a building. The absolute best case scenario, is designing it to fall straight down, instead of starting a game of dominos and taking down every skyscraper.
