The war between Iran and Saudi Arabia has been going on for centuries!

This internal change is just another facet of that war between co-religionists for power in the region.  

The 'Christians' and Catholics killed over 6 million of each other doing the same thing back during the 30 years war time frame!

Our mistake was our reliance and that of Europe on the oil in the region.

With fracking and such, I question whether it is still in the 'National Interests' of the US to continue to participate in their theocratic fight for secular dominance.

If the Europeans prefer Middle East oil and natural gas to Russian sources, let them send their soldiers to get it.  

We'll sell them arms and ammunition, one of our big money makers in the region today.
