I have said this many times, and I will say it once again.
It is a FACT that Greece is the only country that has continously expanded since her liberation, and this at the expense of her neighbouring countries. Greece has never lost territories that were OFFICIALLY recognized as part of her.
All other major Balkan countries - Bulgaria, Serbia, Turkey - have all lost territories at some point. Now how dare you accuse others of expansionism. Greece tried to annex Cyprus too, and if it were not for Turkey, Cyprus would now be a Greek province, much in the same way as Western Thrace, from which my relatives were ethnically cleansed!
