The French sided with the Muzzies over the Spanish/Austrian/Italian/Polish alliance; they also sided with the Lutheran Germans/Scandinavians over the rest of the Catholics in the 30 years’ war.

Isn’t it lovely that Charles needed to strike a deal with the Protestant princes, when the Turks were in Bavaria? At least after 1529, Luther quit preaching that the Muslims were preferable to the Catholics. Sure, it was too late for those poor saps in Bulgaria, Bohemia, Hungary, who were slaughtered while Luther was admiring the Muslims. But what did they matter to Martin?
By the way, the princes who struck the deal to defend Vienna weren’t the ones I meant never helped out in the defense against Islam, obviously. Those princes’ realms eventually reverted to Catholicism. Ever wonder why Austria, Hungary, Spain, Italy, Poland, Portugal and the Balkans all stayed Catholic? Because they understood what the Catholic Church was fighting for... they had faced Islam. In Germany, the split was largely North-South. The North stayed Lutheran, the South stayed Catholic or reverted.
