Shame on you, Turkey, for the Armenian Genocide, the Assyrian Genocide, the Greek Genocide, and even the Italian genocide.
That's right. The last Ottoman sultan Mehmed VI, Mustafa Kemal Ataturk, and President Erdogan are all personally responsible for the actions of Mithridates VI of Pontus (Mithridates the Great) and his decision to kill all the Romans and Italians of Anatolia in 89-88 BC, an event known in modern parlance as the Asiatic Vespers.

Shame on the Turks who didn't live in Asia Minor yet and wouldn't even arrive there until a thousand years later!
Spoiler Alert, click show to read:
The Romans, led by Sulla, kicked Pontus in the arse, though, on several occasions in mainland Greece and then in Anatolia. The First Mithridatic War basically ended in 85 BC with an unfavorable peace treaty for Pontus that had them surrender their new conquests in Anatolia plus a bunch of annual tributary gold to the Roman Republic. Obviously in hindsight it turned out to be an incredibly poor decision by Mithridates VI to antagonize the Romans to that extent, but do you think it was a good or bad strategy for getting the city-states of western Anatolia onto his side? If his armies hadn't lost pivotal battles against Sulla, he could have easily capitalized on the brutal removal of Roman influence in Anatolia and cemented his rule and suzerainty over the region. For a time it probably had the dual effect of cowing those who would dare to challenge him while also appeasing those who didn't want Rome there in the first place, especially the abusive tax collectors, the publicani.
So, was it a wise move in the short-run? Hypothetically speaking, if the armies of Pontus hadn't gotten wrecked by Sulla, it could have even benefited Mithridates in the long run. I know that sounds like something straight out of The Prince by Machiavelli, but it's an honest question. Just how effective was genocide of this scale? We all know that ultimately it only served to enrage the Romans, steel their resolve to launch an invasion into Asia Minor, and put Pontus in its place. That's not always the case, though. Sometimes a group that becomes the victim of a genocide doesn't get to strike back like that or doesn't have the political or military power to do so. It's also the ancient world we're talking about here. There certainly wasn't a United Nations around yet to send the perpetrators a strongly worded letter of their disapproval.
