In the US, media is totally critical of Shiite-majority nations while avoiding any serious critical view of Sunni-majority nations. If that's too opaque, then another way to put it is that the US stigmatizes, sanctions and engages in military interventions in countries that the Saudi government is hostile towards: Iran, Iraq, Yemen and Syria; who are Shiite-majority and Shiite-ruled. The Saudis are themselves Sunni and they treat Shiites as "barely Muslim". Saudi interventions in Oman or Yemen are ignored while Iranian interventions get reported to American audiences.

What is happening in the Middle East is a modern version of the Thirty Year's War. This time, instead of Catholic vs Protestant, it is Sunni vs Shiite.
