Absolutely right. In addition to millions being killed, every single Christian had his/her property stolen and given to Turks. Compensation and restitution should be a major part of the resolution.
Since most of the victims are dead, compensation is moot. Restitution for confiscated property would be up to Turkey. They could follow the example of some Eastern European countries by returning public buildings to their original owners, Churchs, Christian community buildings, things like that, but I wouldn't hold my breath. Financial instruments, bank deposits and insurance policies, there are living heirs and those can be restored. It's the one area the international community, even the US and individual states have leverage. I believe NY Life settled a number of these, at the behest of the State of California.
