The US has been bombing the enemies of the Saudi's more specifically. The Middle East is not one unified place. The only reason the US sanctions Iran is to help the Saudi kingdom.
How is that relevant? Do you think the enemies of Saudi Arabia are stupid? Do you think they don't know it's American bullets and bombs that kill their families and friends?
No, it is just that the Saudi's are a main portion of the Arab population. Not all brown skinned people are the same. I was seeing where you get confused.
