Oh yes, I knew that! But what I can say is that if this one had been, the world would know about it. A grain of 'truth' is always at the centre of conspiracies, it helps to make them seem credible. But a little analysis shows them to be deliberatly misleading.
As an aside, I also think that the trend to blame everything on the Americans, however tenuos a link is hysterical and counterproductive as it detracts from the real problems that the US has caused. It is a bit like crying wolf, if we blame them for everything people will eventually stop believing that they are resopnsible for anything
