Impending next round of Shi'a-Sunni feud.

Iran criticizes Saudi Arabia over Hajj deaths http://www.cnn.com/2015/09/27/middleeast/hajj-pilgrimage/index.html

There has been a long standing feud between the Shi'a and Sunni Moslems since the debate over the succession of leadership in the Islamic faith. There have been two major players in this feud in the modern era-Saudi Arabia and Iran. Now with the hajj stampede this past week, Iran has now criticized Saudi Arabia for what has occurred while Saudi Arabia proceeded to crack back against Iran for putting in their two cents regarding the matter. Now with both Major Islamic sects along with two prominient Islamic nations getting their beef on with one another, looks like the feud could be taken to a new and quite possibly a very bloody one. Yes I'm exploring this topic in Fallout which I'm writing at the present. Imagine if there is an all out war between Iran and Saudi Arabia. Looks like all Sunni and Shi'a Moslems will likely get into the act. With the recent Russian influence in the Middle East the US and Russia could somehow get into the act and maybe fight each othet as well. This is a concern since both nations have nukes and with the recent tensions between the two nations, I shudder to think of the outcome. If China stays out of this they could be ensured of being the lone superpower. Then things become very interesting for sure and I mean this as an understatement...
