What happened was - even by the official version - a conspiracy in the very sense of the word. The question that wasn’t sufficiently answered is who conspired with whom to bring about the events.

Don’t attribute to conspiracy theories what comes down to greed and sociopathy.

I wasn’t. I am just pretty sure that greed and sociopathy go a lot further than you might be willing to imagine.

People profited off the tragedy not because they performed some clandestine bullshit, but because they were always ready to take advantage of just such a situation.

That “clandestine bullshit” has been proposed in the former US administrations in all seriousness way before, see Operation Northwoods. I don’t have a crystal ball to know for sure what happened, but I have zero reason to believe the official version that is full of holes, and think following the money gets you much closer to the truth. And the military industrial complex is full of people who make their whole living off the business of murdering people. Do you really think those would bat an eye at the thought of killing a few thousand americans if it secured their profits for the next decades?
