Sorry I can't help 7mm. I've heard of those "theories" but never gave them much thought.
I was forced to give them some thought, as my 14 year old daughter wanted to watch it and had some very good questions. Therefore the 'urgent' need for hard evidence to debunk the film. Though I am proud to say she is a very ardent President Bush supporter. :) I just needed to make sure the view she was getting was balanced with some good old fashion fact.
