Koprulu Mustafa Pasha is correct.
The video gets everything wrong about what the Ottomans wanted in the 1683 campaign. For decades there had been a frustrating stalemate between the Habsburgs and the Ottomans in Hungary. Then Imre Thököly suddenly showed up. To Constantinople, Thököly provided the one thing they had needed to finally conquer Royal Hungary,
local support. The Ottoman campaign into Austria was an attempt to crush the Habsburgs in one quick war while they still had the advantage provided by Thököly, then convince the ruined Habsburgs to give up all claims to Hungary for once and for all.
Of course, the Kadizadeli preachers urged for the conquest of Vienna. But just taking the city alone would have been a huge feat enough to appease all but the most zealous of the Kadizadeli.
The Ottomans had no interest in Bohemia whatsoever and an
ideological interest in Vienna as a city (not all of Austria).
The video's description of the Ottomans is full of Orientalist cliches:
- A big reason the Ottomans can't advance further into Germany is apparently because "they are in decline" and this decline is permanent and inevitable and all-encompassing in both reality and every possible timeline, neither of which are the case.
- The harem was not the club for daily decadent orgies many Europeans thought it was, and the influence of court women in Ottoman politics was, if anything, a stabilizing force.
- The Ottoman army remained competitive in Europe until the mid-eighteenth century, and technological inferiority was not a big factor in the crushing defeat of 1699. Certainly, if the Ottomans kept fighting regular wars with Prussia, it's rather unlikely their army would fall back as it did IRL.
- The Ottoman economy expanded enormously in the eighteenth century, it was not anything like permanently "crippled" by "guilds controlling its economy."
- The ulema were not uniformly, or even mostly, against Western technology. Actually they quite liked European technology as a rule (while not Ottoman per se, I'm reminded of a Moroccan cleric who quipped about his country compared to France, "our religion is as advanced as their country; our country is as devolved as their religion.")
Anyways, since "the Ottoman province of Bohemia" would never exist, the rest of the timeline falls apart.
