Your conclusions are kind of funky.
The neo-con idea was to "drain the swamp" with Saddam being at the center of the swamp. (By the way I'm not a neo-con and don't support their views.)
Would it have made sense to bomb mecca? Maybe. But there would have been repercussions with that action as well.
One of the best solutions is to be energy independent and not give the Saudis any money and let the kingdom face the wrath of the wahabbi clerics without having any money to pacify them. Of course the left is against drilling for oil, fracking and is against anything that is not clean-energy. A good compromise would be to drill and focus the tax revenue derived from the drilling on improving photo-voltaic paint, tidal power, etc...
By the way this has nothing to do with capitalism - it may have something to do with corporatism but then fascism is not exactly capitalism is it? At least not the capitalism as described by its supporters - Menger, von Mises, Hayek, Samuelson. Now you may think they're mistaken - but at least address the points and views they raise and acknowledge that their conception of capitalism is not the tyranny that some make it out to be.
