This was an interesting discovery on a blog, how this person defines genocide. I think there is a marked tilt in their viewpoint. Of course there are other words that could be used, pogrom and massacre come to mind.
Saddam killing/gassing/shooting Kurds - Genocide
Saddam gassing Iranain troops during the Iran-Iraq War - Massacre
The Islamics of Sudan's little war against the Christians and Animist - Pogrom.
The 1915 killing of Armenians by Ottoman Turkey - Genocide
Pre-20th Century actions against Jews in Europe - Pogroms.
Nazi efforts against Jews in the 20th Century - Genocide
Rwanda - Genocide
Serbians against Croats and Muslims - Genocide
Croats against Serbs and Muslims - Genocide
Stalin's forced deportation of millions to Siberia - Pogrom
