The Shia Iranians and Sunni Saudis hate each other.
“The Shia Iranians and Sunni Saudis hate each other.”
Yes they do, but keep in mind that they tend to hate Jews and Christians even more than they hate each other. And (at least in religious terms) they hate other ‘infidels’ (Hindus, Buddhists, atheists) even more than they hate Jews and Christians.
