Saudis operate under sharia law.
So does Iran. Most Muslim-majority countries incorporate sharia at some level in their legal framework, with many calling it the highest law or the source of law of the land in their constitution. Saudi Arabia, Yemen, Brunei, Qatar, Pakistan, United Arab Emirates, Iraq, Iran, Afghanistan, Sudan and Mauritania apply the code predominantly or entirely.
SIS is about killing everything not SUNNI... shia, kurds, Christians, and non-sectarian other groups.
No, they are not about killing shi'a. They would have to kill the majority of Iraq if that were the case. They occupy Mosul, the second largest city in Iraq. Shi'a make up about 15% of Muslims worldwide.
We agree at some level. Daish and ISIS... they are sunni. Many are those who were with Saddam before his death. They were part of Saddam’s ongoing conflicts against the kurds and shia. GWB installed a Shia government. There is a difference of opinion whether Iraq is more SHIA or SUNNI. Different sources claim different percentages. But yeah.. Iraq is up for grabs. Iran is not up for grabs by Sunni.
Syria is up for grabs and run by Assad who is essentially non-sectarian. Both sides don’t like Assad.
