I think its simpler. There is no one white involved. What is unique about Israel is that most of its population is white so its an issue worth covering (for people backing either side). The same with Ukraine. On the other hand what happens in Eritrea or Sudan or Myanmar or Xinjiang does not matter.
Iran's population is also overwhelmingly pro-West.
