Here's what I think about 9-11.
Usama Bin Laden and his people hated the decadent West. He saw America as the head if the serpent. He wanted to strike the serpent, in a spectacular blow. The 9-11 attack was that blow.
He recruited 20 suicidal maniacs to hijack 4 passenger planes and crash them into the World Trade Center Towers, The Pentagon and a fourth target---probably the White House r US Capitol building.
His plan was spectacularly successful!. Now for the Conspiracy.
During WW II, the OSS, daddy of the CIA developed something called the K.I.S.S Principle---"Keep It Simple, Stupid"
In clandestine operations, set a goal and set a simple plan to accomplish it. That happened with the 4 planes and 19 suicidal maniacs.
From there Conspiracy Theorist have taken over
.Bring down the Towers! How? Thermite-death rays!. But there are 15, 000 people in those buildings, nearly 24/ Details, details!. Then we will make the plane targeting the Pentagon disapear, with all it's passengers, and hit the building with a rocket. Let's take down Building 7. But-but wasn't hitting the Towers spectacular enough? Details-details.
Kiss K.I.S.S. goodbye
