There are people or even a part of a nation, even though it's hard to call them people, who are cold blooded killers which work on the principle of rational and prepared violence. The basis of such inhumane behaviour should be sought in complete nationalist societies in which nationalism becomes the justification for all crimes towards other people.
In order to achieve but also to justify genocide many reasons are given from national threat from another nation, various myths where military victories are celebrated and defeats dramatized, call to revenge, for all economic or other issues the nation which will be attacked is blamed and murders are being staged in order to awaken fear and lust for revenge. All of these examples took place in Bosnia and Herzegovina before the aggression by Serbia and Montenegro. In the same manner, the same scenarios can be seen every day in the media when one of the many terrorised Palestinians, rebel and show some resistance to the Israelite army, they are promptly killed. There we can see a perfect example of manipulation when it comes to killing, in this case of the Palestinians, which is perfected by the Jews.
Genocide done to the Bosnian people, and that to the Palestinian people, is based on the same villainous policy which rests on the fact that the victim is freed from its identity, is humiliated and all attributes of humanity are stripped away and the victim is reduced to something or someone very low, in the case of the Serbs who committed the aggression you could hear: "we must kill all balije!" and among the Jews "we are a holly nation and that is why we must cleanse Israel from the damned animals (Palestinians)!". Among the Serbian ideology of evil the Bosnians are not a nation but a part of the Serbian people which converted to Islam and in the Jewish the Palestinians as people don't exists they are in essence people from Jordan?! All of these claims were created because of propaganda which must justify future crimes solely for one purpose which is creation of "Grand Serbia" or "Grand Israel".
A large part of nationalists have a common characteristic which is primitivism which is in its essence devoid of any sort of intelligence, connection with reality and historical facts. Those people simply don't have the habit nor ability to be educated, nor to research and perceive historical facts. The best example is the usage of the term balija by the Serbs. They don't even know the real meaning of that term, which in the past was a synonym for an agricultural worker in Bosnia, a farmer. Besides that, Bosniak's as the majority in Bosnia and Herzegovina always had a larger percentage of their citizens living in urban and not rural areas. These are only small examples which perfectly explain how nationalism is a fertile ground exclusively among the primitive masses and uneducated people.
Politicians like Slobodan Milošević, Radovan Karadžić, Ariel Sharon or Benjamin Netanyahu belong to a category of so called epileptoid psychopaths, who are usually sadistic and violent in their policy, if they are intelligent. Their priority is the nurturing of primitive nationalism, or what is usually called "American excellence" today in the USA, which is the "food" for people of lower intelligence which turns them into mass murderers, war criminals and psychopaths of every sort. Representations of crime which were undertaken by the Serb soldiers in BiH in some instances exceeded the atrocities of WWII. Civilians and prisoners of war were subject to various types of torture, abuse, they cut their fingers off, ears, hands, legs, genitalia. Decapitation was the most frequent occurrence. Such crimes were done with the help of broken bottles, or old knives in order to prolong the agony of the victim. Girls of all ages were raped and often they would force male family members to rape their mother, sister, grandmother .
The crimes of the Israeli army done to the Palestinian inhabitants are no less horrifying. The thing that is most intimidating is that the Jews created the largest concentration camp in the world where they hold over two million people in the most inhumane conditions in front of the whole world?! We can compare Gaza with the besieged Sarajevo where during that time around 11 thousand people were killed. The fact that is most frightening is that Gaza could end up like Srebrenica which is referenced to by various Israeli politicians with statements like: "the goal of the operation is to return Gaza into the medieval times" or the statement of Gilad Sharon, the son of the former Israeli prime minister Ariel Sharon - "We must raze all of the districts in Gaza!". We see immense hatred in these statements and a clear desire for a new genocide which caused death to millions of Palestinians over the last few decades.
When religion becomes justification for genocide
The role of religion is interesting when it comes to the planning of mass crimes, that concept of God and the holly which is built in the ideology by the people committing the crime serves as just another "justification" why a certain nation needs to be destroyed. Throughout history we have a lot of examples but today the most numerous myths are the Israeli ones, such as the myth of the "sacred nation", the rebuilding of the temple of Solomon or the Serbian one where they claim that they are a "heavenly people" and that even "God himself is a Serb!". Another example is Saudi Arabia which by the establishment of Al-qaeda used Islam with the goal of dominating other countries in the Middle east, creating an impression that their attacks were directed towards other religious groups, but that has changed in the past few years and we are witnessing killing of Muslims by various Islamist groups lead by Al-qaeda with the obligatory exclamation "Allahu Akbar!". Like in the previous examples crimes are justified by fight for ethnically cleansed lend and "free" lifestyle.
Conformism in the service of crime
In psychology the term criminal ruthlessness which always signifies planned and desired crime in which the person is aware of what it is doing. Mass killings and rapes in which Serbian soldiers smirk, jeer and joke on the account of their victims fully fit the profile of social sadists and bullies which have a lower intellectual factor. The cause of such behaviour should be sought in the term "collective consciousness". There is a difference between individuals and collective consciousness, or the consciousness of people in the mass. Both individuals and a mass can be ruthless, but inside a mass we have a new phenomenon, which is responsible for numerous war crimes, and that is conformism. In all major crimes done in Bosnia there is always the same formula: a few real villains which trigger events, and besides them, a mass of faceless conformists. After all fear, cowardice, weak personality and conformism go together. An ideal example is Srebrenica where under the leadership of Ratko Mladić and a few other military personnel, the largest genocide in Europe after WWII was undertaken.
