I dont think i agree with you that osama has turned against the US. The US bought and owns bin Laden so they can pretty much portray him as evil and anti-US for the benefit of US. Speaking of hollywood, here's a perfect example...
this is osama bin laden...
this is someone else, some fat fuck, portraying as bin laden in the 9/11 confession video (i still have the boston herald with the picture of that video on front page and it is the exact same picture of the same person...)
notice the distance between the eye and the nostril of their noses...
this isnt anything conspiracy theory...it is very obvious...now ask yourself...why would they do something like this???
