Nowadays, the CIA and American military's involvement in essentially creating Osama Bin Laden is considered a conspiracy theory. But, on September 11, 2001, it was a verifiable fact. Osama Bin Laden, and al-Qaeda, were trained up by America to aid in the military conflict against Saddam Hussein that resulted when Iraq invaded Kuwait. We call this the Gulf War. Though the narrative has been changed over the last 20 years, there actually was a large portion of the population that wasn't looking forward to another war (truly, the majority of people wanted to strike back, but the minority was a large and vocal one.) I remember seeing coverage on CNN that included actual video footage, recorded in the Middle East during the Gulf War, of Osama Bin Laden, and other members of al-Qaeda, training with American soldiers. This was reporting meant to dissuade America and to prevent a declaration of war. Obviously, it wasn't successful.
I was 17 when the towers came down, and was very political active at the time, especially for my age. I remember these things vividly. So, where's the conspiracy theory come in? Go try to find information about this. You won't find a video, an article, or a single still. You'll find a post-9/11 crackpot theory about a CIA agent, an American, named such-and-such who was a stand-in for Osama, which has so many holes in it that it's laughable. What you won't find is any information about America, Osama, al-Qaeda, and the Gulf War.
It's our Tiananmen Square. One of them, at least.
