I also object to the sentence "the people are cowards and cannot face up to the facts of their own complicity in the death cult". That is hyperbole and grand-standing all around.
Yet, I am sad to disagree with you. Because it is definitely an interesting question why we spend so much on military. Specifically, it is interesting how this relates to industries that benefit from this spending. Though it is also quite relevant to study popular sentiment towards this spending. However, I do not think one should go to conspiracy level explanations here. If one were to go there, it would take heaps and heaps of evidence.
To convince me, and perhaps the rest of the world, start by making smaller claims that are easily proven. Then you can build up to stronger claims that aren't proven but are at least corroborated by evidence.
Or you might just be an astroturfing russian-payed troll to make us distrust government, but I'd like to think otherwise.
