There is no proof of any of this, nothing concrete presented to the public.
Mr Majestyk, you should give a fuck. You cannot use something as an example, and then when someone asks why there is no proof respond simply with "who gives a fuck". They are all theories and conjections, but are an important part of fighting a war or starting one. This is the same way the US went to war with Iraq, or rather occupation since no declaration of war was ever passed. Present a bunch of supposed intelligence, with no proof or backing but expecting the public to just take your word for it. Usually, they do because they just don't know any better and don't expect their government to take advantage of their trust. It happens everywhere.
In Iran in 1979, the people revolted thinking they were ousting the Shah to bring in a saviour. Someone to bring revelation and salvation, to free them from suppression. What did they get? In Germany in 1933, Hitler became Chancellor and the people didnt know he was going to release a war machine that would cost millions upon millions of lives. In America in 2001, the people were promised that the man who was responsible for attacking their nation and causing such a devastating loss of life would be caught and punished. In 2008 he is still at large and excuses are made as to why.
Patriotism is the last refuge of a scoundrel.
