Ask the pontians and armenians.o
Yeah we can ask. The pontian and greek issue about Ataturk was a population exchange with Greece, where the Muslims of Greece were deported to Turkey and the Greek of Turkey to Greece. Yes, it was a very traumatic event on cultures' behalf but it was an agreement between the two countries.
The thing about armenians was an entirely different issue. Ataturk was an ordinary officer in Gallipoli while the genocide was being executed by the Ottomans in the east.
Actually, Ataturk and Venizelos became best friends after the wars, their good relation reflected on the politics of the two countries for some time.
