The preoccupation with Iran's brand of Islamism while turning a blind eye to or supporting Sunni Islamism reflects this skewing of priorities. Iranian clerics have Israel as their main target. Wahhabi Sunni clerics have Europe and America as the main target of their hatred. None of the 9/11 attackers were Iranian or Shia. Neither were any of the ISIS-inspired recent attacks on America or its NATO allies.
Saudi Arabia was definitely touched by Cold War.
Fast forward to today: I trust Trump’s navigation of US/Saudi relations. And this new Saudi prince on the scene...he’s an interesting one. For now he irks me less than Assad/Khomeini/Erdogan.
