Let the Arabs, Iranians and the US fight it out....burn them all in the coming wars. Get your economy up, take charge and be the new US in the region.
Once bloodshed has reached its peak or/& ended, broker deals between the two extremes in the region. Take control of Makkah & Medina....limit Iranian influence or just curb it to the ground.
Formup an actual Muslim alliance, against the West (or just the US), with the help of Turkey, Malaysia, Indonesia etc....clean up the Muslim world of Western backed dictators (like Sisi)...expand your own sphere of influence.
I'm sure the EU won't interfere in all of this....they're not like the US and more cautious when they know they're going up against a near peer adversaries.
Bring in a new age of prosperity with the dismantling of neocolonial grip all around the Muslim world.
Obviously, it's easier said than done but you gotta have some backbone which Pakistan right now severely lacks imo.
Why not just overthrow both of them??
We know these regimes aren't going to last long....either the Zio-US backed Saudis or the rabid Mullahs.
