This one, would this frontier be viable long term just like the one draw on otl that stands up to our day? This one would leave the Safavids with easternmost anatolia, all of the caucasus and mesopotamia. This means that the Safavids have a black sea port through georgia, the shia turkmen of anatolia, a breadbasket region like mesopotamia which is far more useful and near the center of power for Iran then the Ottomans and includes the really holy places of Karbala-Najaf-Kufa being for the Safavids a mix Egypt (breadbasket), Hejaz (holy places), and the balkans (right next to center of power, easy to exploit but a frontier territory). This also means that most of their frontier pases through the arid mountains of eastern anatolia, the syrian-iraki border, and than it sorta dissolves itself into the huge syrian and arabian deserts.
A map with elevation, but with the romans holding western georgia, this may be a little more plausible Ottoman-Safavid border, after all Istanbul-western georgia are communicated through sea and Tabriz/Teheran through mountains, but I would like to hear ideas about the plausibility and long term consequences of both borders compared to otl.
