OK; so what has Greece done for America?
Unlike Germany and Austria-Hungary, Turkey was in a position to continue fighting (regardless of how hopeless it may have been). Russia’s surrender had left plenty of troops for Turkey to use elsewhere; the Allies’ treatment of Turkey after WWI probably saved them from having to fight Turkey again in WWII. We didn’t take Hamburg or Munich from Germany; no reason to take Istanbul from Turkey. Who would they have awarded it to? Greece, who fought at the very end of the war? Over the centuries it had become part of Turkey; there was no way to undo that.
Greece gave America both democracy and Christianity. You want more than that? As the Greeks say, “what do you want, a son-in-law with two eyes?”
