In my opinion America should not get involved in this ancient religious fued between Shiite and Sunni. PH is predominantly Sunni,Obama’s root is a Sunni, and Valerie known as the little President is half Iranian, a Shiite. It is her dream to my opinion to unite US-Iran joint operation in Iraq. US military industrial complex armed the rebels, Al Quida to put down Assad of Syria. The rebel known as ISIS succeeded getting the half of Syria, instead of putting down Saad, they moved to take over half of Iraq with US supplied weapon. This Moslem religious fued started when Mohammad died, he did not appoint his replacement whether a Sunni or Shiite to lead the Moslem world. Until this time,they are killing its other. Iraq originally Sunni controlled under Sadam Hussien and US replace it with Shiite Prime Minister Al Maliki.Iran a Shiite had already send his Iran Republican guard to Iraq. If we are going to help Iraq, in the long run Iran will be the beneficiary.
