If the Valentino is right about the crucial role of relatively small ethnic or military groupings in the cruelest offences of the twentieth century, then genocide/mass killing may appear not to be the secret it would seem. And if its nature can be seen in lucid terms that refer to a wide range of examples, then maybe something can be carried out to avert it. This is, first of all, the real aim of all genocide scientists. By the way, they care about the pragmatic consequences of their work in stopping the killing as they are with its purely scientific value (Miller). Summing up all phenomena connected with human activity - especially genocide all over the world in the twentieth and nineteenth century – one can surely feel blue and disappointed. Though in a sarcastic manner, Valentino has evaded this partially by including in his work what he calls "mass killing," or "the intentional killing of a massive number of noncombatants" (Valentino). You are surely interested how massive these killings are? Here Valentino gives the definite figure of "at least fifty thousand intentional deaths over the course of five or fewer years," though if his theory is proved to work, he claims, this figure should reduce as well (Valentino). The main point is not in definite number (and one of the cunnings of the UN’s Genocide Convention is that it does not require any researches revealed in specific numbers on a genocide studying). The main point is to understand how the mass killing of guiltless, defenseless people becomes the policy of some states.
