Moore follows his GUT, by which I mean his Grand Universal Theory: Bush is to blame for everything. Because of Bush, the Saudis secretly run US policy. Because of Bush, the Taliban were in bed with Texas energy executives. Because of Bush, the Taliban got toppled.

Whoa, hold up a minute, I thought he was all pals with the Taliban. The Saudis certainly were, which is why they opposed the liberation of Afghanistan. But by now Moore’s moved on to pointing out that Bush’s Afghan stooge Hamid Karzai used to work for the Texas energy company panting for that big Afghan gas pipeline.

But hang on, I thought the Texan energy guys already had the Taliban in their pockets and were funded by the Saudis. "Connecting the dots" is all very well, but not when you’ve got more dots in your picture than Seurat.
