Basically, what do you think are the things needs to be done for the Safavids to hold onto Iraq from the 1510s and on? Considering the natural borders of Al-jazira deserts, do you think Safavids could have held on militarily against Selim and stabilized the border along the lines of Rome-Sassania?
Also if Persia holds on to Iraq (at least southern Iraq) indefinitely, would Iraq be sufficiently integrated into the idea of 'Eran'? What are the chances of some sort of Persian language and culture taking root in Iraq? Seeing that Iraq is quite heavily Shia, would it be considered an integral part of the realm like Azerbaijan?
Seeing that Iraq was some neglected borderlands under the Ottomans, could it regain it's status as the economic engine of Persia like its heyday under the Sassanians?
Finally, after the inevitable collapse of the Safavids some two hundred years later. What are the chances of it's successor state keeping Iraq as an integral part of 'Eran'.
