I think the goal of Greece’s foreign policy relating to Turkey at some point is going to focus less on expanding Greek boarders and more on creating, making, and helping allies with similar geopolitical concerns. Greece standing alone is weak. A Greece who is friends with Armenia, Cilicia, Pontus, a Christian and Alawite Antioch State, Kurdistan and Lebanon that stand together in fear of revanchist Turkey is strong. Not all those states are going to exist obviously but I’m just running through a list of possible nations to be part of this defensive league. Russia and Egypt are also possible members and would add a lot of extra power to said alliance as wellSo while everyone's been discussing how much Turkish clay that could be peeled off for Greece to claim, I've been wondering:
What exactly is gonna keep Turkey from being on a constant revanchist rampage trying to reclaim it? Because that's gonna happen. They are not gonna take the massive loss of that much land easily or well, so...
Greece needs to do something, less Turkey just go full on Grudgement levels of hatred against them.
I will second oca2073’s concept of encouraging a cultural divide of some sort in the Ottomans could also work, although I’ve no clue how that might be accomplished in a practical sense. But the Greeks somehow co-opting a “Rumelian” cultural identity for Turkish people in the Balkans and tie them to Greece it would certainly help with the population issues the Greeks would have if they just kicked them all out.
I’m have no clue how to accomplish that though or if it’s even possible. I’m hoping that Greece is willing to accept Muslim Greeks like the Vallahades as Greeks in this timeline and I’d consider that a nice victory. I’ve said that before that allying with Bektashi muslims makes a lot of sense in this universe. The Greeks can always use more manpower and tax payers and the Bektashi are no friends of the ottomans at this point in time. Also many of them still speak Greek or Albanian and are Muslims with a lot of Christian traditions mixed in so they’d be easier for your average Greek to relate with. They’re a great first step towards Muslim acceptance and integration in Greece.
