1.Classification People are divided into "us and them".
"The main preventive measure at this early stage is to develop universalistic institutions that transcend... divisions."
2.Symbolization "When combined with hatred, symbols may be forced upon unwilling members of pariah groups..."
"To combat symbolization, hate symbols can be legally forbidden as can hate speech".
3.Dehumanization "One group denies the humanity of the other group. Members of it are equated with objects, diseases or terrorists."
"Local and international leaders should condemn the use of hate speech and make it culturally unacceptable. Leaders who incite genocide should be banned from international travel and have their foreign finances frozen."
4.Organization "Genocide is always organized... Special army units or militias are often trained and armed..."
"The U.N. should impose arms embargoes on governments and citizens of countries involved in genocidal massacres, and create commissions to investigate violations"
5.Polarization "Hate groups broadcast polarizing propaganda..."
"Prevention may mean security protection for moderate leaders or assistance to human rights groups...Coups d’état by extremists should be opposed by international sanctions."
6.Preparation "Victims are identified and separated out because of their ethnic or religious identity..."
"At this stage, a Genocide Emergency must be declared. ..."
7.Extermination "It is 'extermination' to the killers because they do not believe their victims to be fully human".
"At this stage, only rapid and overwhelming armed intervention can stop genocide. Real safe areas or refugee escape corridors should be established with heavily armed international protection."
8.Denial "The perpetrators... deny that they committed any crimes..."
"The response to denial is punishment by an international tribunal or national courts"
For genocide to happen, there must be certain preconditions. Foremost among them is a national culture that does not place a high value on human life. A totalitarian society, with its assumed superior ideology, is also a precondition for genocidal acts. In addition, members of the dominant society must perceive their potential victims as less than fully human: as "pagans," "savages," "uncouth barbarians," "unbelievers," "effete degenerates," "ritual outlaws," "racial inferiors," "class antagonists," "counterrevolutionaries," and so on. In themselves, these conditions are not enough for the perpetrators to commit genocide. To do that—that is, to commit genocide—the perpetrators need a strong, centralized authority and bureaucratic organization as well as pathological individuals and criminals. Also required is a campaign of vilification and dehumanization of the victims by the perpetrators, who are usually new states or new regimes attempting to impose conformity to a new ideology and its model of society.— M.
