I didn’t actually believe this, but it was fun to entertain the idea.

Here’s why. At the time, there were a bunch of very odd coincidences. I’ll do my best to remember the best of them.

• The CIA/NSA (one of the “secret” agencies) put out a budget report showing a large amount of money that was not trackable, in the billions.
• Coincidentally, the section of the pentagon hit by the “plane” was reportedly where financial records were stored.
• By “plane”, I mean object. If you watch the 1 video that got out (all other videos were confiscated) from the nearby gas station, the thing that hits the pentagon does not look like a plane but instead a missile.

Next!

• reportedly, the owner of the twin towers took out a massive insurance policy against the buildings the day or week before 9/11 (I forget exact timing)
• also, the building was covered in asbestos, the cost to remove was in the billions, and the cost to keep the building occupied always also increasing

Next!

• building 7 (I think that’s the right one) collapsed under what appeared to be demolishing conditions
• building 7 was never hit by a plane or anything else, it just dropped like it was purposefully demolished

Edit: forgot one!

• the towers were obviously hit by planes, we have plenty of video evidence of this. The controversy is around how the towers actually fell. This is where the “jet fuel can’t melt steal beams” meme comes from.

There are more, but it’s been 20 years and my memory is hazy.

Overall, there were some oddities around the whole event that, when allowing yourself to think completely outside of reality, make sense as to why it was an inside job.

Finally, personally I believe the Saudis did it in cooperation with Bin Laden and their goal was to bankrupt America. They did a pretty good job, from their perspective.

I can't vouch for the veracity of most of your content but I wanted to add that building 7 was also announced to have collapsed before it actually did.
