To all those wondering the Geography is vastly different compared to that of our world. In fact as a case and point in the witches world the Gulf Neruoi War takes place in the nation of Ostman and sitting adjacent to it is Persia: a nation that Geographically speaking consists of both Iran and Iraq since historically it never did become two separate nations and to some degree still holds many of it's historical, cultural and ethnic heritage even far into the 20th century.
Or in regards to Persia this would be the case in the current Second Neruoi War Cannon Continuity, it seems that for the Gulf Neruoi War Project it seems to either be following the older, retconned Second Neuroi War Geography and hasn't been updated or alternatively Persia may have been overrun by the Neruoi somewhere between the 1940's to 1990's, consumed all the countries natural resources (specifically the land and mineral resources within)and the whole nation as a result fell into the sea after it was processed, thus resulting in the inland sea east of Ostman.
