This documentary is very harsh with facts. Just to point out two:
There has never been a prooven connection between 9/11 and Afghanistan or the Taliban; the main reasons for invading afghanistan were merely economical benefits, such as securing a gas-pipeline bringing gas from the caspian region to the Bay of Begal for shipping.
Furthermore both, Osama Bin Laden AND the Al-Quaida network have repeatingly denied all bounds to either planning and commiting the 9/11 terror attack; which is unusual and up to date the only terror-attack the commiting force has not claimed responsabilty for. Even the idea of Bin Laden hiding in Afghanistan on a longterm basis turned out to be a myth such as the whole “war-on-terror”-thing, which simply has to be concidered as a agressional imperial way of defclecting economical goals to install the USA as a number one world power. Just the same such as the Babylon Empire (Alexander the Great), the Roman Empire or, last but not least, the Third Reich in Germany. All of those three have one thing in common. Guess what. Next!
