if by latins u mean the occupation in the 13th century, no offence but this is the second most ahistorical thing i have ever heard. fistly the latins were christians, they didnt occupied all of the state, they didnt used to "steal" young children from their families to turn them to their elite troops, they didnt had so big taxes for everything ,even for living, they didnt used to make as bow when one of them passes the road, the patriarche was preserved only for making the greeks less unlikely to revolt, it was an ottoman puppet and it declared every rebbelion as its enemy,in 1821 the low rank priest stood against such a declarion and were the first to begin the rebbelion. in my opinion if the reason not to take those areas was the fact that no much greeks live in the area in the year 2012(in the 20th century the greeks in east thrace were much but they were wiped out by undercovered turk operations or ultraislamists) shall i remind u that 10 million greeks live outside our todays borders and can be called anytime to live to the new areas conquered.
You'd be lucky if you get 100,000 people to return out of that 10 million.
