Although the Greeks considered themselves Romans for centuries, they had to abandon this Roman identity and become Greeks in order to gain the support of European countries.
European countries can only assist the Greeks in reclaiming the lands of ancient Greece but cannot help the Romans reclaim the territories of the Roman Empire. Helping the Romans reclaim the Roman Empire would imply that Italy, Spain, the United Kingdom, and other nations should also be "reclaimed" by the Romans, creating an extremely awkward and contradictory situation. European countries have no territorial issues with ancient Greece, but they would face various territorial issues with the Roman Empire.
Although the Greeks considered themselves Romans for centuries, they had to abandon this Roman identity and become Greeks in order to gain the support of European countries. But isn’t it a tragic thing when one’s identity is not something one can decide for oneself? The Greek identity has actually disappeared for several centuries, only to be restored by European countries in modern times. I could be wrong, but I always feel like it's a group of Romans playing the Greeks and a group of Arabs playing the Egyptians.
