From the book:

Through this genocide and the forced deportation of the Greeks, the nationalists completed the Young Turk’s program – the Turkification of Turkey and the elimination of a pretext for Great Power meddling. The Young Turks’ policies were also those of the nationalists, although carried out with less bloodshed and greater cleverness. Through war, genocide, deportation, and the flight of refugees, both regimes reduced Turkey’s 1914 population from around 20,000,000 to 13,660,000 in 1927, as counted by Turkey’s first full census.- R.J. Rummel, p. 235.
