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.
Here is a translation a friend of mine was able to do.
World View/Outlook
About 40 years after “Strike Witches.” Even after the great war, humanity has continued to encounter on numerous occasions the menace of the mechanical army known as Neuroi. The sole force that can equal and surpass the fighting power of the Neuroi is the strong power of the Witches, according to the intellect/wisdom of humanity. In August 1990, three massive Neuroi nests appeared in the airspace above the Arabian Peninsula governed by the “United Kingdom of Jazeera.” The country/region was overrun (by the Neuroi) despite frantic resistance, and the world’s most productive oil fields were captured. As many (human) lives were mercilessly lost, and the world was again threatened by the menace of the Neuroi, peoples from many countries and regions joined forces, and the “multinational allied army” was formed. The witches formed the vanguard of the army. To liberate the Arabian Peninsula, and protect the world, they would unleash their fierce fighting power again.

The wealthy, oil producing country of the “United Kingdom of Jazeera” controls the entirety of the Arabian Peninsula region. The geography is based on that of “Strike Witches Horizons”
