Leslie Davis was truly a great diplomat and an incredible human being.
Until Genocides are not widely recognized and stopped. Those who commit them are not punished, they are going to happen again, as they did during 20th century. Hitler used Armenian Genocide to convince others that atrocities committed by Nazis are going to be forgotten. Hitler's quote: "Who, after all, speaks today of the annihilation of the Armenians?"
It is a shame that US did not officially recognize Armenian Genocide yet, even though most of the civilized world did and most of the US State legislatures did.
Germany was one of the main allies of Ottoman Empire when Armenian Genocide occurred and they only recognized Armenian Genocide of 1915 in 2016. 101 years after it happened.
