Greek Orthodox Arabs are traditionally very supportive of Arab Nationalism & are usually tied with Sunni Muslims. Possibly because the French gave the Uniate Christians preference over the Orthodox, thus pushing the Orthodox closer to the Muslims.
Middle Eastern minorities have different strategies:
(I’m only talking about the minorites from where I’m from, the Levant.)
Maronites - separation.
Greek Orthodox - Arab Nationalism.
Alawites - Syrian Nationalism.
Jews - throw their support into the small separatist state of Lebanon, supportive of the state in Syria.
Shi3a - same as the Jews in both countries.
Armenians: supportive of the state. (Syria, Lebanon, Israel.)
Circassians: supportive of the state.(Syria, Israel.) Bad blood between them & the Arab Nationalists.
Druze: shifting alliances in Lebanon, Syrian & Arab Nationalism in Syria, supportive of the state in Israel. Bad blood between them & the Maronites.
