Some of that is true. The sides are now being chosen up for the war that is coming, basically for who will control the vast oil deposits in Syria, which is no longer a country really, and in Israel (newly discovered).
Saudi (Sunni) and Iran (Shiite) are mortal enemies for control of the Middle East. Erdogan sees Turkey as the caliphate eventually and will end up siding with Russia and Iran against Saudi, us, and Israel. Maybe not us.
So there’s that old brother-against-brother thing too. Not to mention everyone against Israel.
Thirty years ago, an insider told me that there was oil off the coast of Lebanon and also off the coast of Vietnam. Humm?
