If both parties scrap their mutual ego, i dont see any reason why Iranian entry into GCC is prevented hence there is no reason why GCC with Iran and maybe Pakistan and Turkey can't become the next BRICS.
Unity is the key to burn to ashes the collective misery and patheticness of ummah. If both paries can't see that we have become from an empire streached from Spain to India , an empire of inventers , thinkers , law makers , surgeons , conquerors , scientists , engineers , businessmen , traders , scholars , kings , architects to terrorists , human traffickers , pirates , kidnappers , dictators , extremists , honor killers , oppressors , rioters , illiterates , oppressed , genocided , refugees , drug smugglers and what not.
If its not enough to give up your ego than my logic cant produce a substance but a mass muslim genocide thats about to happen which WILL wake you up.
