Saudi Arabia represents the Sunni Islamists, while Iran represents the Shiite Islamists. All other countries that are interested parties will take their cues from these two countries. Apparently their on and off relationship goes back to Mohammed and his death.
So for awhile, they co-existed, but Saudi Arabia put to death some prominent Shiite Islamists, and now they are cutting off ties with each other.
Here’s what’s interesting – we kind of have our own Sunni versus Shia battle in America. Who were Bush’s friends? The Saudis. Who is in the White House with Obama? Iranian born Valerie Jarrett. It’s probably a big deal about nothing, but it gives food for thought.
