I think it is mainly about oil supply. We have enriched the Sheiks so lavishly with our foreign oil dependence (refusing to drill here) that they turned it into a political force. Jim Baker has always been a pro-Arabist which is now hand in glove pro-Islamist. Then you have a majority of American Jewry not giving a hoot about what happens to Israel - “They brought it on themselves”, so they say. Just as they described the victims of the first Holocaust. The White House is totally pro-Islamist.
Agreed oil is king. When you analyze it all its a typical mid-east cluster. Little if anything makes good sense.
The saudi royals live in luxury unknown to anyone until they created it. But, they play both sides funding madrassas,terrorism,wahhabism,sharia,you name it they are complete whackjobs all of them.(no caps necessary on any of those words)
